haiku_loader: Fix wrong size of gBootGDT on x86_64.
The BOOT_GDT_SEGMENT_COUNT was based on USER_DATA_SEGMENT on both
x86 and x86_64. However, on x86_64 the order of the segments is
different, leading to a too small gBootGDT array. Move the define to
the arch specific headers so they can be setup correctly in either case.
Also add a STATIC_ASSERT() to check that the descriptors fit into the
array.
Pointed out by CID 1210898.

x86[_64]: Separate bootloader and kernel GDT and IDT logic
From now on bootloader sets up its own minimal valid GDT and IDT. Then
the kernel replaces them with its own tables.

Implemented long mode setup/switch code, the bootloader can now start the 64-bit kernel!
The setup procedure is fairly simple: create a 64-bit GDT and 64-bit page
tables that include all kernel mappings from the 32-bit address space, but at
the correct 64-bit address, then go through kernel_args and changes all virtual
addresses to 64-bit addresses, and finally switch to long mode and jump to the
kernel.

Added mmu_allocate_physical(), which allocates a specified physical memory
range.
