[clang-format] Support of TableGen tokens with unary operator like form, bang operators and numeric literals. (#78996)

Adds the support for tokens that have forms like unary operators.
- bang operators:  `!name`
- cond operator: `!cond`
- numeric literals: `+1`, `-1`
cond operator are one of bang operators but is distinguished because it has very specific syntax.
