Separate the Text node's generated glyphs into separate vector table rows (#2821)

* Separate glyphs into Vector data rows

* Fix `String Length` node

- Properly count characters with
`str.chars().count()` instead of bytes `str.len()`
- Change `String Length` node's output to `u32`

* Apply transform on instance instead of applying it when drawing the glyph

* Add checkbox to enable/disable per-glyph instances

* Tooltips
