Initial AArch64 port (#205 )

* Initial aarch64 port

* Enable chainload on aarch64

No changes necessary since it's all UEFI anyway.

* Add specification for Limine protocol for aarch64

* PROTOCOL: Specify state of information in DT /chosen node

* common: Add spinup code for aarch64

* common: Port elf and term to aarch64

* common: Port vmm to aarch64

Also prepare to drop VMM_FLAG_PRESENT on x86.

* protos: Port limine boot protocol to aarch64

Also drop VMM_FLAG_PRESENT since we never unmap pages anyway.

* test: Add DTB request

* PROTOCOL: Port SMP request to aarch64

* cpu: Add cache maintenance functions for aarch64

* protos/limine, sys: Port SMP to aarch64

Also move common asm macros into a header file.

* test: Start up APs

* vmm: Unify get_next_level and implement large page splitting

* protos/limine: Map framebuffer using correct caching mode on AArch64

* CI: Fix GCC build for aarch64

* entry, menu: Replace uses of naked attribute with separate asm file

GCC does not understand the naked attribute on aarch64, and didn't
understand it for x86 in older versions.
