## Summary
- fall back from database-applied `SPU Decoder: Recompiler (ASMJIT)` to
`Recompiler (LLVM)` on ARM64 builds during boot
- log the fallback in `fixup_settings()` instead of letting SPU
initialization fail later
## Problem
`Need for Speed: Most Wanted [BLES01659]` receives `SPU Decoder:
Recompiler (ASMJIT)` from the config database. On ARM64 builds that
decoder is unsupported, which caused RPCS3 to abort during SPU
initialization with `Unsupported spu decoder` while the UI remained on
the loading screen.
## Validation
- built RPCS3 locally on macOS Apple Silicon
- booted `BLES01659` through the database config path with the custom
per-game override temporarily removed
- verified the log now shows the ARM64 fallback warning and `SPU
Decoder: Recompiler (LLVM)` instead of the previous fatal error
- observed the title proceed past the old boot blocker into active RSX
program compilation

Prevent invoking more than utils::get_max_threads() active thrreads at a time.
Windows sees more than utils::get_max_threads() active threads as potentially malicious behavior and lowers the program's overall CPU time.
- LLVM can't handle the select pattern we use to avoid poison values for large shifts
- So let's just use the intrinsic to avoid poison values altogether for now

Fully implements cellSysmodule and sets it to HLE by default.
There is an undocumented function that decrypts the OpenPSID. There
doesn't seem to be any information about this on the PS3 dev wiki or
anywhere else, so I thought I mention this separately.
Refactored `SHUFB` by moving the byteswap optimization prior to the target specific path. Also separated the shuffle and special index constants calculation into separate steps in order to reduce code duplication.
Added a number of TODOs as this refactor revealed some of optimizations opportunities. None of which has been added as this refactor intends to minimize new behavior.
The "Fill more block info" re-decode indexed result.data[(ia - lsa) / 41] instead of / 4 (its companion decode uses / 4), so it read the wrong word and corrupted the per-block reg_const / reg_val32 constant propagation.
