Upgrade WebRender to e491e1ae637b2eed1e7195855d88357e5eb3ddf9 (#30323)
* Upgrade vendored version of WebRender * Patch WebRender: upgrade version of gleam * Restore hit testing implementation * Fix WebRender warnings * Adapt Servo to new WebRender * Update results * Add a workaround for #30313 This slightly expands text boundaries in order to take into account the fact that layout isn't measuring glyph boundaries.
