sceFontCharactersRefersTextCodes fills a 64-byte FontTextCodes with the
order and code of a text character and keeps the current, start and
term characters at +0x28, +0x30 and +0x38. The traversal follows the
PS4 11.00 libSceFont.sprx disassembly posted in the review of #4050,
which implemented the same rules: Refers never compares the character
with the term and returns null for a clustered or synthetic character,
sceFontTextCodesStepNext returns null at the term after visiting it,
sceFontTextCodesStepBack returns null at the start character, and both
steps skip synthetic characters. Null from StepNext at the end of the
chain and from StepBack at the head of the chain is assumed and not
covered by the report.
The signatures follow Orbital's IDA type database and SharpProspero. A
null cursor or output returns null as in KytyPS5; a null text character
throws. guest_font_tests gets configure_windows_unwind so the expected
exception reaches the test on Windows.

The call was an unimplemented stub. It now writes syllable state 0 and
returns OK for every character outside the Thai block, where a PS4
firmware 11.00 libSceFont measures 1, 3 or 4; Thai characters throw as
not implemented. A null character or result returns
SCE_FONT_ERROR_INVALID_PARAMETER, and a null character writes 0 to a
non-null result, as measured. The signature follows SharpProspero.

The second argument is an out pointer to the writing's letter step, as
KytyPS5 and the SharpProspero bindings declare it. It was filled as a
letter step struct, which wrote 64 bytes over the caller's 8-byte
pointer. The letter step now lives in the writing and the call stores
its address, or null when there is no current step.
