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kern: enforce end of dram == end of partitions (move our probably outdated KTraceBuffer to new location)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

kern: put rela in bss ...

NOTE: This saves ~0x4000 of space at the cost of crimes against the linker script.

ams: the copyright^H^H^H^H^H^H^Hmplex plane is the algebraic closure of the reals

kern: update Initialize0 for new arguments/randomization semantics

kern: support dynamic resource expansion for system heaps/events/sessions.

kern: kill the interrupt task manager thread

kern: improve single-step around user-exception entry

kern: optimize hw-single-step management

kern: add hardware single step extension

kern: update initial cache management to match latest kernel

kern: fix enormous whoops

exo/meso: update for gcc 11 compatibility
