framebuffer: report display EDID data

This allows to see the display in Screen preferences, and know its DPI
and physical size (as much as EDID data can be trusted). This
information could be used to compute the default font size, for example,
so it's important that all drivers provide it whenever possible.

build: Define _BOOT_MODE once and for all in ArchitectureRules+BootRules.

Previously it was spread all around the tree, and was not defined
consistently for all boot objects (there were a number of boot modules
which did not define it, but did include headers which checked for it.)

Now, as it is handled in SetupBoot which is invoked for all boot objects,
it will be applied consistently throughout. We can thus drop the manual
additions of it from all Jamfiles.

Distinguish KERNEL_ARCH_DIR from KERNEL_ARCH.

On x86_64, the KERNEL_ARCH should really be "x86_64", but it was "x86"
as the architecture sources/headers directory is shared between 32 and 64 bit.

Should not be a functional change on any platform outside x86_64.

ARM64 Jamfiles, missed in previous commit

* Use generic c versions of memset and memcpy
Wwrite fast asm for that later, therefore no need for arch_string.S
* Disable FDT and DTB until ARM64 is ready
(WIP: do it later)
* use ELF64

haiku_loader.efi: update for riscv64

* Added MMU page table generation.
* Added optional FDT device detection and passing to kernel.
* Add platform address translation stubs to bios_ia32

efi: Refactor CPU code to be arch-specific

* Migrate some platform agnostic architecture code into
boot/arch from efi/arch. This helps to avoid conflicts
between kernel and boot sources as well.
* Conflicts between arch_cpu in efi and kernel code means
bootcode really should *never* directly use kernel arch
headers. (other platforms don't, which is why they don't
have this same issue)
* We carefully thread any needed kernel headers (namely
assembly helper macros) into the bootloader headers without
mixing in the whole conflicting kernel/arch headers.
* ARM now properly get its cpu init code called, and we
progress further into the EFI bootloader.
