Without system font files, sceFontOpenFontSet returns
SCE_FONT_ERROR_FONT_OPEN_FAILED and logs `file=(none)` for each call.
Some titles then fail far from the cause: Astro's Playroom (PPSA01325)
lays out text with the failed set and stops on an out-of-heap or invalid
texture assertion (#7714). The first such open now prints the font set
and the directory searched to stderr, with how to supply the fonts.

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.

libSceFont and libSceNpEntitlementAccess located the executable
through /proc/self/exe, which macOS does not have, so finding the
system fonts and the entitlements file threw there. Use
_NSGetExecutablePath and resolve the path with
std::filesystem::canonical on macOS. Linux and Windows are unchanged.

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.

sceFontSetScriptLanguage, sceFontGetScriptLanguage,
sceFontSetTypographicDesign and sceFontGetTypographicDesign threw. With
the signatures SharpProspero declares, a font handle now keeps the
language set for each script and the feature set for each typographic
design, under the handle's lock, and returns them, with 0 for one never
set. They do not change shaping or rendering yet; TechnicalDebt records
the assumptions.

sceFontGetCharGlyphMetrics and sceFontGetRenderCharGlyphMetrics set the
vertical bearing and advance to zero although the glyph is loaded with
FT_LOAD_VERTICAL_LAYOUT. The library's own text writing steps the pen by
that vertical advance, so every character of vertical text was placed on
the previous one.
The vertical metrics now follow the FreeType driver's metrics of a
rendered glyph: FreeType's vertical advance, and for a face without
vertical metrics a bearing of half the horizontal advance left of the
horizontal bearing and of half the advance left over by the glyph height.
guest_system_font checks every metric of a square glyph at 100 pixels.

Detach the device cache buffer attached by sceFontAttachDeviceCacheBuffer. The signature is taken from the IDA type database of Orbital: it takes the library, a pointer to receive the buffer and a pointer to receive its size. When no cache buffer is attached, it reports NOT_ATTACHED_CACHE_BUFFER. If the library allocated the buffer itself and no buffer pointer is passed, the memory is freed. The owned bit is cleared and device_cache_buf is reset to null.
PPSA01325 stops on sceFontGlyphDefineAttribute right after generating a character glyph: it sets attribute 0x11 to 0 on that glyph, deletes it without using it, and draws the character with sceFontRenderCharGlyphImageHorizontal. The meaning of the attributes is unknown, so the call checks the glyph and ignores the rest; TechnicalDebt lists it under silent stubs.

Every library CMakeLists.txt ended with the same block removing -static,
-static-libgcc and -static-libstdc++ from CMAKE_EXE_LINKER_FLAGS on MinGW,
because core/libs/CMakeLists.txt only removed them after adding the library
directories. Remove them before the libc and library directories are added
so each directory inherits the stripped flags, and drop the 52 copies.

Report the spacing the writing line applies: the modelled line places
each run at the sum of the previous advances, so every space is 0.

Report the face's glyph count and the glyph index of a character through
the library's driver; the FreeType driver gains its glyphs_count entry.

Create, destroy, clear, write runs, step through them and read the
line metrics, following KytyPS5. Layouts from SharpProspero.
