Splits the asset archive into a compressed (DEFLATE) zip and an
uncompressed (STORED) zip back to back behind a small header, instead of
one plain zip. DEFLATE-compressed zip entries aren't reliably seekable in
libzip, which caused locale string lookups (repeated rewind/reopen of the
same entry) to silently skip content on Dolphin specifically. Uncompressed
entries don't have that problem, so locale files now go in the stored
archive without needing to buffer the whole thing in memory.
Adds tools/asset/pack as the new packer (replacing the plain
`tar --format=zip`), a shared assetdsk.h/.c opener used by all platforms,
and a second ASSET.zipStored handle with fallback lookup in assetfile.c.
Confirmed working: Linux, PSP (PPSSPP), and Dolphin-FAT (Wii DOL under
-a LLE) - the original Dolphin locale lookup failure no longer reproduces.
EBOOT.PBP packing was a POST_BUILD step with no dependency on the asset
pak, so an assets-only rebuild could silently leave a stale dusk.dsk
embedded. cmake/targets/psp.cmake now repacks EBOOT.PBP via a properly
tracked custom command depending on the executable, PARAM.SFO, and
dusk.dsk (and correctly embeds Dusk.prx rather than the raw ELF when
BUILD_PRX is on).
Separately, libzip's zip_source_filep_create (lazy seeked FILE* reads)
proved unreliable on real PSP hardware, corrupting reads of the embedded
PSAR (first EINVAL, then zlib data errors) even though the packaged data
was verified byte-perfect. assetInitPBP now reads the whole PSAR into
memory once and uses zip_source_buffer_create instead. Confirmed working
on real hardware.
