kern: add missing debug mode check to WriteDebugProcessMemory

ams: deduplicate static initialization logic

kern: fix vi devicename missing in HsSupported device list

kern: correct TotalUserPhysicalMemorySize (closes #1710)

kern: be a little more consistent about pragma GCC location

Minor header fixes to reduce parsing issues with Clang (#1700) ...

* Work around Clang's incomplete C++20 support for omitting typename

* vapours: fix Clang error about missing return in constexpr function

* stratosphere: fix call to non-constexpr strlen in constexpr function

strlen being constexpr is a non-compliant GCC extension; Clang
explicitly rejects it: https://reviews.llvm.org/D23692

* stratosphere: add a bunch of missing override specifiers

* stratosphere: work around Clang consteval bug

Minimal example: https://godbolt.org/z/MoM64v93M

The issue seems to be that Clang does not consider f(x) to be a
constant expression if x comes from a template argument that isn't
a non-type auto template argument (???)

We can work around this by relaxing GetMessageHeaderForCheck (by using
constexpr instead of consteval). This produces no functional changes
because the result of GetMessageHeaderForCheck() is assigned to a
constexpr variable, so the result is guaranteed to be computed
at compile-time.

* stratosphere: fix missing require clauses in definitions

GCC not requiring the require clauses to be repeated for member
definitions is actually a compiler bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96830

Clang rejects declarations with missing require clauses.

* Fix ALWAYS_INLINE_LAMBDA and parameter list relative order

While GCC doesn't seem to care about the position of the always_inline
attribute relative to the parameter list, Clang is very picky
and requires the attribute to appear after the parameter list
(and before a trailing return type)

* stratosphere: fix static constexpr member variable with incomplete type

GCC accepts this for some reason (because of the lambda?) but Clang
correctly rejects this.

KScheduler big brain strat for mdscr_el1 cfg change

dmnt2: detect thread name, add monitor get mapping(s), increase buffer sizes

kern/dmnt2: allow retrieval of process info via extension ...

This also fixes ctrl-c break in gdbstub, and fixes crash on unknown monitor cmd.

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

kern: fix 32-bit light ipc svc handler asm ...

Nintendo used to do what we were doing because the function wasn't directly in the handler table,
but we've always been directly in the handler table, so we were trashing the last four arguments to light ipc
when called from aarch32. Nothing uses this, but needed to be fixed.

kern: optimize and bring into line with N our pstate.i management

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

kern: other dmbs in kernel were already dmb ish

kern: add (and use) generic KSystemControlBase

kern: add toggleable support for 40-bit physaddr caps

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

kernel_ldr: bring initial cache flush in line with Nintendo

kern: reflect nintendo cache management behavior for initial processes

kern: devirtualize KReadableEvent::Reset, KWorkerTask::DoWorkerTask

kern: devirtualize most things that are free to devirtualize (see #1672)

kern: use optimized red black tree finds for remaining holdouts

kern: devirtualize several KAutoObject functions

kern: KCacheHelper: better reflect nintendo coremask clearing logic

kern: devirtualize remaining vcall for class token/dyncast

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

kern: use new AtomicRef, use Atomic<bool>

util: better match true std::atomic semantics

kern/util: use custom atomics wrapper to substantially improve codegen

kern: use 13.0.0 revised KLightLock logic
