Merge #4925

4925: Syntax highlighting for escape sequences in strings r=matklad a=ltentrup

I have added a new semantic token type `ESCAPE_SEQUENCE` as the LSP specification does not seem to have an appropriate token type. This may actually be a regression for some users, as the TextMate Rust grammar has a scope `constant.character.escape.rust` which highlights escape sequences (which caused problems with semantic highlighting, see #4138).

Fixes #2604.
