When tokenizing markup (e.g. HTML) element attributes can have quoted or unquoted values (e.g. `a=b` or `a="b"`). The `ATTR_VALUE` tokens were capturing the quotes, which was inconsistent and also affected source-mapping. Now the tokenizer captures additional `ATTR_QUOTE` tokens, which the HTML related parsers understand and factor into their token parsing. PR Close #28055
