boot: Support booting in EFI mixed mode

The kernel provides a ".compat" PE section that contains a list of
compat entry points with their respective arches. This entry point
does all the heavy lifting to support running 64bit kernels when
the UEFI firmware is 32bit.

Note that the EFI handover protocol code in linux_x86.c does not
need any adjustments as it already correctly calls the 32bit handover
code.

Fixes: #17056
