FirstBootPrompt: Replaced %Distroname% with filler text

The unofficial builds used %Distroname% directly and showed that to the
users, which does not look great. Instead use different wording that
simply avoids mentionning the OS name in de-branded builds.

- Small lingustic change: "Try Haiku" sounds a bit less awkward than
"Try out Haiku" and conveys the same exact meaning.
- Updated copyright note.

FirstBootPrompt: Improved language, make distro-aware

Replace "Haiku" with "%distroname%" for non-official builds i.e. forks.
The forker will have to replace the "*Distroname*" that is now shown
on unofficial builds.

FirstBootPrompt: even more fixes

The previous code tried to add a boolean to the quit requested message,
but that is not propagated from the app to the window QuitRequested, so
it didn't work. Instead, split the task between the app and the window'
QuitRequested functions.

FirstBootPrompt: Another fix for #16525

If we quit the app before handling the "reboot requested" message, the
system doesn't reboot.

FirstBootPrompt: some NULL pointer checks

Should fix #16525

FirstBootPrompt: Exiting is now possible

- Exiting the window when the Desktop is not running will result in a reboot.
- Otherwise, the window will just close ordinarily.
- A confirmation box pops up before rebooting.
- Made other optimizations for running FirstBootPrompt on the Desktop.
- Moved some definitions to the header files.
- Added "UsePrivateSystemHeaders" to the Jamfile.

(Thank you, PulkoMandy!)

At 12pt, we try to fit a 640x480 display. But at larger font sizes we

FirstBootPrompt: more layout fixes

ResizeToPreferred will only relayout the window once. Further calls will
not change anything, even if the text in the BTextView changed. So make
sure to compute the preferred size with a very high text view, and only
then, set the (rather short) english text.

This makes the text view large enough to fit the text in all languages,
and the window never changes size.

FirstBootPrompt: fix layout

In some languages, the buttons would end up outside of window bounds, as
changing the BTextView content does not automatically update the window
size (even with B_AUTO_UPDATE_SIZE_LIMITS). So, we need to manually call
ResizeToPreferred after changing the text.

However, this exposed another problem: the view size is computed using
GetHeightForWidth, with a width as small as allowed by layout
constraints. In our cases, there weren't much layout constraints so we
would end up asking the text view to compute its height for a width of
52px, leading to a very high window. Add some explicit sizing
constraints to the text view and language list to make sure we get a
sane size.

Also tweak the layout a little to allow the keymap menu field to be
wider than the language list view, and make the window not resizable as
that makes it much easier to keep things under control and there isn't
really a need to resize it.

apps: Convert to using Set*UIColor.
