IRJit is now the base the IR JITs share: the frontend, the table of guest
blocks, and compiling and invalidating them. IRInterpreterJit and
IRNativeJit are the two kinds. Only IRInterpreterJit keeps IR, in its arena,
along with its dispatch loop and per-block profile.
The native JITs no longer keep the IR they compiled from. The debugger and
the --jit-profile report compile a native block's IR again when they want it,
on a copy of the frontend's state, which gives what ran unless the code or
that state has changed since.
IRBlockCache and IRBlock become JitBlockTable and JitBlock: where each block
came from, the page lookup for invalidation, and the block shadow entry (an
arena or native code offset, depending on the JIT). One IRJitDebugInterface
serves both JITs, taking the MIPS code from the table and the IR and host code
from the JIT, in place of the native JIT's own debug interface.
The native backends don't see the table at all. They compile a span of IR for
a block number and start PC, and keep what they need about their own blocks
(start PC, code offset, which block starts where, for linking) next to the
exits they already tracked. The register cache takes the instructions
directly.
The tracer's block index now goes into the IR before the block is stored, so
native blocks get it too. The unused FindByCookie goes. TestJit checks that
the native JIT keeps no IR, and can still show it. The JIT stats overlay no
longer shows IR for the native JITs. MIPSState can't be copied, now that it
owns its JIT.

The global MIPSComp::jit becomes MIPSState::jit, created and deleted by the
state it runs. JitAt() compiles with the JIT of the state it's handed, so
the dispatchers no longer go through a global. Code that is about the main
CPU by nature (the UI, the crash handler, the disassembler's symbol lookup,
the JIT harness) uses mipsr4k.jit.

Shows the number of blocks, how full the native code space and the IR
arena are, and how many times each filling up cleared the cache.
The "Ran out of block numbers" message was logged for both of those, and
there is no block number limit. It now says which one filled up.
Also hide the GPU profile and allocator overlays by value on backends
that lack them. Cutting the last two off the list had been hiding the
framebuffer list since it was added after them.

EmuScreen only draws the crash info when an exception was recorded, and
showed just the Resume/Reset/Back buttons otherwise. Several ways of
stopping the core with CORE_RUNTIME_ERROR recorded nothing:
- A bad memory access in JIT code that MemFault can't skip, either
because it can't decode the host instruction or because ignoring is
only configured through the exception action, went to the crash
handler, while Core_MemoryException returned early under the default
Ignore action. A halting access is now always recorded.
- HLEReturnFromMipsCall on a corrupt stack, and a failed LoadExec, set
the state directly. They now go through Core_HLEError, which records a
new HLE exception type with a message that the crash screen shows.

div.s now maintains fcr31's Cause.Z and (when the trap is masked) sticky
Flag.Z bits, in the standard MIPS bit positions. Only a finite non-zero
dividend counts, so 0/0, inf/0 and NaN operands are excluded per IEEE 754.
When the guest has the trap unmasked, the new Core_FPUException() reports it
with the usual module suffix and MIPS call stack, and fd is left unwritten as
hardware would. That's gated behind a new developer setting, off by default:
PSP threads start with fcr31 = 0x00000e00, i.e. three of the traps already
enabled, and games divide by zero without meaning anything by it. The fcr31
bits are updated either way, so what the game reads back doesn't depend on
the setting.
Interpreter only - the JITs are unchanged, and none of this is reachable
under them.

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
This adds a per-game graphics option, `DisplayRefreshRate`, to override the display refresh rate.
It defaults to 60 Hz, and is located in Dev tools.
Games using variable timesteps benefit from higher refresh rates.
Closes#19319
