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.

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.

On Windows 10 a file with a mapped view cannot be deleted, and FreeType's
Windows stream keeps the face's file mapped, so removing SST-Bold.otf threw
and ended guest_system_font. Moving it out of the font directory leaves
nothing at the original path and works on every host.

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.
