Update E999 to show all syntax errors (#11900)
## Summary

This PR updates the linter to show all the parse errors as diagnostics
instead of just the first one.

Note that this doesn't affect the parse error displayed as error log
message. This will be removed in a follow-up PR.

### Breaking?

I don't think this is a breaking change even though this might give more
diagnostics. The main reason is that this shouldn't affect any users
because it'll only give additional diagnostics in the case of multiple
syntax errors.

## Test Plan

Add an integration test case which would raise more than one parse
error.

Ruff Python Parser

Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.

Try out the parser in the playground.

Python version support

The parser supports the latest Python syntax, which is currently Python 3.12. It does not throw syntax errors if it encounters a syntax feature that is not supported by the target-version. This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
