Henrik Rydgård 7b409af50f MetaFileSystem: spell out how to add a mount without breaking savestates 
The positional serialization means adding a mount silently invalidates every
existing savestate unless its prefix is added to the skip list, which is exactly
how flash1: broke them. Write down the rule, and note that renaming or removing
a mount isn't something this scheme can handle at all.

Henrik RydgårdandClaude Opus 5 729653bf42 Fix loading savestates made before flash1: was mounted 
78ef1eae82 added a flash1: mount, but MetaFileSystem::DoState serializes the
mounts positionally - one section each, with no length to skip by - so a state
written before that commit has one section fewer than we now have mounts.

The existing count check assumed a single missing entry could only be pfat0:,
which was the previous mount added this way. So it took the skipPfat0 path,
skipped pfat0's section while still only looping n times, and ended up making
n-1 DoState calls against n sections. Everything after that read shifted, and
the load died with "Failure at DirectoryFileSystem".

Make the "these were added later" set explicit and ordered instead, and iterate
over the mounts rather than over the saved count, so the number of DoState calls
matches the state regardless of which of them are missing.

Verified against Wipeout Pure (UCUS98612): both save slots report n=9 against 10
mounts and fail to load before this, and load after, in both the app and headless.

Henrik Rydgård 78ef1eae82 Instead of flash0directory, have a NAND subdirectory under PSP, where you can keep flash0, flash1 etc. 
Also make it configurable via command line.

returned 0.

0 should be considered a valid handle ideally, but left it never returning
0 to simplify cleanup in some areas.
