Add support to play from a BD Drive (currently only on Windows) (#18648)

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`
