arch/x86/boot: Jump to payload in protected mode
* On ARCH_RAMSTAGE_X86_64 jump to the payload in protected mode.
* Add a helper function to jump to arbitrary code in protected mode,
similar to the real mode call handler.
* Doesn't affect existing x86_32 code.
* Add a macro to cast pointer to uint32_t that dies if it would overflow
on conversion
Tested on QEMU Q35 using SeaBIOS as payload.
Tested on Lenovo T410 with additional x86_64 patches.
