Jonathan Brouwer 404ee74367 Rollup merge of #154235 - bb1yd:simplify-delim-check, r=fmease ...

remove unnecessary variables and delimiter check

Zulip discussion: https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/question.20about.20lex_token_tree_open_delim.20in.20rustc_parse/with/580552157

In `lex_token_tree_open_delim`, after calling `self.lex_token_trees(/* is_delimited */ true)`:
 - If the delimiters are well-balanced, the value  popped from the stack will always equal to `open_delim` and `pre_span`.
 - If the delimiters are not balanced, `self.lex_token_trees(/* is_delimited */ true)` will return an error so this branch will not be reached

Therefore `open_delimiter` and `open_delimiter_span` can be removed.

Test `tests/ui/parser` all passed
