Use HarfBuzz to get glyph bounding rectangle

For consistent cross-platform results that also matches our glyph
advances since platform functions might be using hints which we don’t
use.

Keep platform-specific implementations as fallback since HarfBuzz
internal font functions (that we use) did not support glyph extents for
fonts with CFF table before 2.3.0.
