feat(libSceTextToSpeech2): fail Open and Close without a speech engine

[SleglJan]

What

sceTextToSpeech2Initialize fails because AnyPS5 has no speech engine (boykopovar#1374). The other seven exports throw NotImplemented: boykopovar#1374 made six of them throw on the assumption that a title only reaches them after a successful initialization and open, and sceTextToSpeech2GetSystemStatus (boykopovar#301) throws too. PPSA11386 (007 First Light) does not: it calls sceTextToSpeech2Initialize (a param starting with 0x2000000, as PPSA01317 passes), gets EOPNOTSUPP, then calls sceTextToSpeech2Close (with a pointer argument) and stops on sceTextToSpeech2Close not implemented; with only Close failing it calls sceTextToSpeech2Open next and stops there.

• sceTextToSpeech2Open and sceTextToSpeech2Close now return the same EOPNOTSUPP (0x8002002D) as sceTextToSpeech2Initialize. With both failing, the title continues its start-up.
• The console's codes for these calls without an initialized engine are unknown; TechnicalDebt's unknown-function-info line now covers all three functions and records that Close receives a pointer the declaration without parameters ignores, and the library line names the PPSA11386 call order.
• Speak, Cancel, GetSpeechStatus, GetSystemStatus and Terminate still throw: no title has been seen calling them without an engine.

Overlap: no open pull request changes libSceTextToSpeech2.

Tested

• Linux (CachyOS, kernel 7.2.9, GCC 16.2.1), Release with BUILD_TESTING=ON, this branch on main 3d1a7d9: guest_text_to_speech2 passes; of the full suite, 686 of 687 pass, and agc_driver_dcc_keys_first_write fails the same way without this change (it links none of the changed files); tools/check_conventions.py --base upstream/main and git diff --check pass.
• GuestTextToSpeech2.cpp (from feat(libSceTextToSpeech2): report the speech engine as unavailable boykopovar/AnyPS5#1374) now checks that Close and Open return 0x8002002D after the failed initialization and that Speak and Terminate still throw, where it checked that Open throws; failures print to stderr. Making Open, Close or Terminate return 0 fails the test.
• PPSA11386 v01.018.000 in a bubblewrap sandbox, on the stack of 007 First Light (PPSA11386) on Linux: start-up stops in order and the PRs that pass them boykopovar/AnyPS5#2523's stops comment (branch explore/007-2026-10-10, main 17d69d1 plus the PRs listed there): without this change it stops on sceTextToSpeech2Close not implemented; with exactly this change (Terminate still throwing) it reaches 1429 shader-cache misses, executes its first 43 draws and submits its first flip; presenting that flip stops on a bindless image table limit, tracked in 007 First Light (PPSA11386) on Linux: start-up stops in order and the PRs that pass them boykopovar/AnyPS5#2523.
• Fork CI on main 3d1a7d9, run 38041364610: Linux (690/690) and the relinker jobs pass; on Windows 696 of 698 pass, and the two failures, guest_memory and guest_file_vector (exit code 0xc0000409), fail the same way in main's own Windows CI (run 38041959161 at 6675e60).
