Add injections for tagged template literals (#15984)

Browse source 
This PR adds syntax highlighting support for `css`, `html`, `js`,
`json`, `sql`, `ts`, `yaml` and `yml` in `javascript`, `typescript` and
`tsx` languages where the contents of tagged template literals are now
highlighted.

This does not actually enable language features (like LSP support), it
only does syntax highlighting.
