Fixes regression from #18546 and #18679.
## Problem
The is_from_yml ISO branch constructed iso_archive unconditionally,
bypassing the cache check inside add_game, making the cache write-only
for yml-sourced ISOs.
## Fix
Added a lightweight index cache entry (iso_path + "//index") storing the
subdir list + mtime. On hit, skips archive construction entirely. On
miss, walks as before and writes the index
Append to `CMAKE_PREFIX_PATH` and `CMAKE_SYSTEM_PREFIX` instead of using `include_directories()` and `link_directories()`.
This avoids include/link path
pollution and reduces clashes with vendored dependencies. This means that conflicting homebrew packages no longer have to be unlinked to build rpcs3, as system paths are searched last.
0.85 elfs break here due to them not having a version header offset.
Very unlikely these elfs will ever load but its useful to be able to decrypt them at least.

Follow up of #18345 to add support (currently only on `Windows`; see
notes below) for playing a PS3 disc game directly from a Blu-Ray Disc
Drive.
### HOW IT WORKS:
- The BD drive can be added as any other game so from `VFS games` or
from `Add Games` menu. In case it is selected from `VFS games`, any
attempt to write files is discarded, e.g. file `Disc Games Can Be Put
Here For Automatic Detection.txt`
- It scans the default redump keys folder `<rpcs3>/data/redump` (it
currently needs to be manually created due it is not yet provided by
rpcs3 installation) to find a matching decryption key
### NOTES:
- Support is currently provided on `Windows` where I can fully test it.
I cannot test under other OS. However, the additions needed for the
other OS are limited only on `fs::file.h/cpp`. In particular inside the
following new functions:
- `bool is_optical_raw_device(const std::string& path);`
- `bool get_optical_raw_device(const std::string& path, std::string*
raw_device = nullptr);`
- Icons etc. are always refreshed (ISO cache cannot be used due `mtime`
on raw device is not available and any cache check would always fail)
- Code in `ISO.h/cpp` needed some rework to properly manage a read on a
raw device (alignment on offset, size and memory is mandatory). The BD
drive needs to be detected as a file, not as a folder
### MINOR FIXES:
- Fixed wrong specifier used in logging on `ISO.h/cpp`
