Abdessamad Derraz 11da070128 chore: recale the profile refs onto their pins
Upstream moved under 145 profiles: 679 refs shifted and 452 followed a
renamed file, against 6,483 that still anchor where they were written.
The recale rewrites the located ranges only, keeping the annotations and
the sentences that carry them, and 106 pins advance in the same commit
because refs and source_commit name one revision or the profile
describes two at once.

Nothing here was guessed. The 183 refs that are CHANGED, GONE or
AMBIGUOUS are untouched, and the 57 profiles holding them keep their old
pin until someone reads the diff: profile_sync refuses to recale a
profile while any of its refs needs a re-read. trident kept its pin too,
its annotated ref being one the writer will not rewrite.

notes: |
Mu emulates Palm m500, Palm m515, and (with EMU_SUPPORT_PALM_OS5)
Tungsten T3. A Palm OS ROM dump is required. The core selects the
ROM filename based on the "OS Version" core option:
Palm m500 / Palm OS 4.0 -> palmos40-en-m500.rom
Palm m515 / Palm OS 4.1 -> palmos41-en-m515.rom (default)
Tungsten T3 / Palm OS 5.2 -> palmos52-en-t3.rom
Tungsten T3 / Palm OS 6.0 -> palmos60-en-t3.rom
ROM path: RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY + "/" + osVersion + ".rom".
No hash or size validation; the code reads whatever file is present.
The bootloader is optional and ignored for Tungsten T3.
Supports no-game mode (boots Palm OS desktop from ROM without content).
