Text: Separate glyph caching procedure

Previously glyph caching was done during text rendering, but that would mean lots of swapping between rendering stuff to the cache and then immediately afterward rendering to the display. There would be a swap per each new glyph.

Now the entire document's glyphs are precached at once when a request is finished. Glyphs are also cached in larger batches when new text needs to be drawn.
