bsp/x86_64: Minimal bootable BSP

Current state:

  • Basic context initialization and switching code.
  • Stubbed console (empty functions).
  • Mostly functional linker script (may need tweaks if we ever want to move away from the large code model (see: CPU_CFLAGS).
  • Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for UEFI-awareness.

In short, the current state with this commit lets us boot, go through the system
initialization functions, and then call user application's Init task too.

Updates #2898.
  • Property mode set to 100644
