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
