Fix strips text offset when zooming VSE timeline
Glyph cache is cleared by UI_view2d_zoom_cache_reset, when zooming V2D, but is
required to calculate text height in UI_view2d_text_cache_draw
This caused text in strips to "jump around"
There was a comment in UI_view2d_zoom_cache_reset:
While scaling we can accumulate fonts at many sizes (~20 or so).
Not an issue with embedded font, but can use over 500Mb with i18n ones! See
[#38244].
