## Message

```
Use `Vec` instead of `SmallVec` for `glyphs` field of `ShapedRun` (#30664)

This glyphs field is usually larger than 8 elements, and SmallVec is not
efficient when it cannot store the value inline.

This change also adds precise glyphs run preallocation in some places
`ShapedRun` is constructed.

Release Notes:

- N/A
```
