[BUG] SKTypeface.GetGlyphs has changed meaning in v2.80

[mattleibow]

Description

Previously, calling SKTypeface.GetGlyphs(...) would basically cast the incoming pointer to the type specified by the encoding. So, for a UTF32 encoding, it took the pointer and cast to uint32_t*. The new way is to "convert" to UTF32.

This is a breaking change and needs to be fixed.

Old: https://github.com/mono/skia/blob/v1.68.3/src/ports/SkFontHost_win.cpp#L2044
New: https://github.com/mono/skia/blob/v2.80.0/src/ports/SkFontHost_win.cpp#L1897

What actually happened under the hood was that the typeface handed all encodings. However, in v2, this was changed and only handles UTF32, so I redirected the logic to SKFont which does the conversion. This was incorrect.

Code

See code in: toptensoftware/RichTextKit#15

Expected Behavior

GetGlyphs(int*, Utf32) should not convert the data to UTF32.

Actual Behavior

Conversion.
