Attachment: Bug 2090465 - Batch simple glyph spans in general text fitting.

Sum simple non-space glyphs without break flags in a compact loop when
spacing, hyphenation and additional wrapping opportunities are absent.
Retain ligature boundaries and reset trailing-whitespace state after a
non-space span. Skip buffer refills when neither spacing nor hyphenation
data is needed.

This optimization is independent of fused fitting and glyph measurement.

Closing this for now as perf improvement is unclear.
