Parse triple quoted string annotations as if parenthesized (#15387)

## Summary

Resolves #9467 

Parse quoted annotations as if the string content is inside parenthesis.
With this logic `x` and `y` in this example are equal:

```python
y: """
   int |
   str
"""

z: """(
    int |
    str
)
"""
```

Also this rule only applies to triple
quotes([link](https://github.com/python/typing-council/issues/9#issuecomment-1890808610)).

This PR is based on the
[comments](https://github.com/astral-sh/ruff/issues/9467#issuecomment-2579180991)
on the issue.

I did one extra change, since we don't want any indentation tokens I am
setting the `State::Other` as the initial state of the Lexer.

Remaining work:

- [x] Add a test case for red-knot.
- [x] Add more tests.

## Test Plan

Added a test which previously failed because quoted annotation contained
indentation.
Added an mdtest for red-knot.
Updated previous test.
