kern: move KTargetSystem into .rodata, split init/verify

kern: allocate all TTBR0 pages during init, use procidx as asid

kern/ldr: enable the use of relr for relocations

kern: pass kernel base from KernelLdr to Kernel

kern: update KMemoryRegionType values for new ids + SecureUnknown region

kern: add speculation barriers after eret

kern: remove unnecessary fields from InitArgs (0x80 -> 0x40)

kern: on second thought, move vectors back to end of text

kern/ldr: move crt0 into .rodata

kern: pass ini1 size from loader to kernel, remove slab memset from init0

mesosphere: remove nostartfiles from specs files (should only be passed to linker wrapper)

kern: minor cleanup (thanks @liamwhite)

kern: refactor init (kill identity map, merge cpu on logic)

kern: move SecureAppletMemory/KPageBuffer heap into the ResourceRegion

kern: increase stack region size when thread resource limit is increased

kern: implement K(Secure)SystemResource

KScheduler: fix documentation mistakes

kern: turns out changing base address gives pretty elfs but breaks relocs

kern: codegen tweaks, now that we're no longer -Os

kern: update for new hw maintenance semantics

kern: implement new thread context/fpu semantics

kern: enforce end of dram == end of partitions (move our probably outdated KTraceBuffer to new location)

ams: support building unit test programs on windows/linux/macos

kern: fix minor assembly bugs, avoid unnecessary function call in KScheduler hotloop

kern: audit (and fix) our hardware maintenance instructions to match official kernel

kern: implement 13.1.0 kernel changes

kern/test: add wip qemu-virt board support to mesosphere

kern: enable lto for global instants (saves about a page in deduplicated code)

kern: optimize timespan -> tick codegen, improve .text layout

kern: avoid constexpr init for many objects (avoids unnecessary memory clear) (#1668)
