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.

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.

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.
