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.

(cherry picked from commit c4dcbe4403dc635fde2a823dec311a939816cefc)
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.

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.

sceFontOpenFontSet failed for every set type, so PPSA21564 drew no text
in system fonts (the title screen copyright line, credits, button
guides). It now loads the set's primary font file from
ANYPS5_SYSTEM_FONTS, or anyps5-fonts beside the executable: console
files under their own names first, then openly licensed substitutes
(Noto Sans, Noto Sans Mono, Noto Sans Thai, Noto Sans CJK). The
PS5-only JG2 set types are accepted.
System font handles use the system font context. Their faces are
loaded by FreeType in host memory: about 1 MiB per CJK face does not
fit the font memory the title sizes for the console's fonts, and
sceFontCreateRenderer then failed with ALLOCATION_FAILED. Handles of
the same font file share one copy of its bytes.
Implement scePthreadGetschedparam and scePthreadSetschedparam on top of
the thread priority, POSIX utimes and fsync on top of sceKernelUtimes
and sceKernelFsync, and sceUserServiceGetAccessibilityZoomFollowFocus
like the other accessibility queries. Add the remaining imports of
PPSA12544 as unimplemented exports and record unknown NIDs and
signatures in the technical debt.

Return the kerning between two character codes at the render scale of
the font, the one set by sceFontSetupRenderScalePixel and
sceFontSetupRenderScalePoint, and fail with NOT_BOUND_RENDERER when no
renderer is bound. sceFontGetKerning keeps its behaviour and shares the
FreeType lookup.

Report the horizontal and vertical resolution kept in the font handle's
style block, as set when the font is opened (72 dpi) or by
sceFontSetResolutionDpi. Error handling follows the other handle getters:
an invalid handle or two null outputs fail and clear the outputs.

Ported from shadPS4 (GPL-2.0-or-later) with system fonts removed, stubs made to throw,
and sceFontCloseFont implemented.
