Debugger: Add Inspector UI controls for edit mode.

InspectorWindow:
- Add buttons to control edit mode, and helper functions to maintain
their state.
- Implement listener hook for memory change events, to track when
requested memory writes are completed, and update the view accordingly.

Together with the previous batch of commits, this implements the first part
of #9708.

Debugger: Extend MemoryView listener interface.

MemoryView::Listener:
- Add extra hooks for notifying listener of internal mode changes.
Implement accordingly in InspectorWindow.

Debugger: Add page protection indicator to inspector.

InspectorWindow:
- We now display a label indicating if the currently inspected block
is writable or not, so the user knows whether it's possible to modify
the contents.

Debugger: Rework expression parsing API.

ExpressionInfo:
- No longer stores an explicit result type (this is inferred from
evaluation of the expression itself now).
- Introduce class ExpressionResult for returning the result of an
expression computation. This can currently take the form of either
a primitive value, or a value node object.
- Adjust UserInterfaceListener and ExpressionInfo::Listener to take
the above changes into account, and correspondingly adjust all
callers/listeners.

CLanguageExpressionEvaluator:
- Introduce child class Operand. This subsumes the functionality that
was previously in the separate Number class, and can represent a
primitive value, a value node or a type. Also has functionality to
implicity handle type promotion/inferring when performing calculations
between operands.
- Adjust expression parser to operate in terms of Operands rather than
Numbers. This allows a number of improvements, most notably that an
expression can now return a value node as a result rather than only
a primitive number. This capability isn't yet fully used, but paves
the way for future uses such as an expression that evaluates to a data
member, a global variable, or an arbitrary pointer of a particular type.
- Various cleanups/simplifications that were possible as a result of the above
changes.

ExpressionEvaluationWindow/ExpressionPromptWindow:
- Remove type menu field, since the expression API no longer uses it.

Adding/removing expressions in the VariablesView is temporarily disabled,
pending some further rework there to properly handle the new result object.

Debugger: Fix #11430.

InspectorWindow:
- Inherit from Team::Listener and implement hook for thread state
change events.
- On thread state change, if the new state is stopped, and we have
an active block, release it, and ask to re-inspect.
- Factor out helper function for updating the active block.
- Always ensure the MemoryView is updated when we change blocks.

MemoryView:
- Clean up acquisition of target memory block.

This ensures that the block data is kept up to date when stepping
through code with an inspector window open.

Debugger: Cleanup.

Team:
- Remove expression evaluation event / listener hook. This doesn't
really belong to the Team anyways.

UserInterfaceListener:
- ExpressionEvaluationRequested() now takes an ExpressionInfo object
rather than the individual subcomponents.

ExpressionEvaluationJob:
- Notification of expression evaluation completion is now handled
via the info object's listener interface rather than the Team.

Others:
- Adjust all users of expressions to set themselves up as
ExpressionInfo::Listener subclasses, and consequently add themselves
to the respective info object when requesting evaluation. This
significantly simplifies various things, and also ensures that no
one accidentally gets notified of an expression they didn't actually
ask for, which could occur with the previous Team-based listener
interface. Make all other required adjustments for new interface
usage.

No functional change intended.

Debugger: Adapt expression eval users to async interface.

Factor out message constant for expression evaluation completion,
as multiple places will be using that.

ExpressionEvaluationWindow:
- Check for expression match immediately in listener hook, and
don't bother dispatching to the message loop in such a case.
Simplifies some of the other code.

InspectorWindow / WatchPromptWindow:
- Rather than attempting to evaluate an expression directly,
we now defer to the async interface. Clean up and adjust accordingly.

TeamWindow:
- Adjust window creation calls due to parameter changes.

This leaves only the CLI dump memory command to be adapted.

Fix crash in InspectorWindow.

- In the case where retrieval of a memory block failed, InspectorWindow
didn't handle the notification. Consequently, it never removed itself as
a listener from the failed block, nor did it release its reference for
it. Consequently, if one attempted to retrieve data from the same block
again, walking the listener list would crash due to the already-deleted
entry in the list.

- The success case had the same problem with regards to not removing its
listener, but was masked by virtue of the inspector currently being the
only user of the memory block manager, so in the latter case the blocks
would be properly released/destroyed and the aforementioned walk would
never occur.

- Adjust locking a bit to ensure that manipulating the listener list
always happens with the team lock held.

- Style fixes.

Add listener interface to MemoryView.

- When the target address of the memory view changes, an attached
listener is now notified. This lets the inspector window's text input
keep in sync with the current address when keyboard navigating the
memory view.

Debugger: Coding style: normalize naming, some whitespace fixes

* TeamUISettings[Factory] -> TeamUiSettings[Factory]
* GUITeamUISettings -> GuiTeamUiSettings
* GUISettingsUtils -> GuiSettingsUtils

Reworked GUI settings storage.

- Simplified things so each window simply records all its settings into
a BMessage, which is what ultimately goes into the actual UI settings.

- Added settings storage/retrieval to the various sub views of the
team window. This means that the column widths/positioning on all
views hosting a column list view are now also preserved and restored.

Save and restore the inspector window's frame + mode settings.

* Actually start rendering the memory data. Still has some drawing glitches
when scrolling though, will look into those tomorrow. Also doesn't yet
highlight the location which the target address actually points to within
the block.

* Introduce TeamMemoryBlock[Manager]. These provide an interface to raw memory
page data of the target team.
* Jobs: Add RetrieveMemoryBlockJob which performs a background read of the
target team's memory. Used by InspectRequested() to perform the actual work.
* TeamDebugger: Added InspectRequested() hooks to allow clients to ask for
a memory read to be performed.
* Introduce InspectorWindow and MemoryView to form the basis of a memory inspector.
As yet these are more or less stubs and not yet hooked in.
