Preserve quote style in generated code (#15726)

## Summary

This is a first step toward fixing #7799 by using the quoting style
stored in the `flags` field on `ast::StringLiteral`s to select a quoting
style. This PR does not include support for f-strings or byte strings.

Several rules also needed small updates to pass along existing quoting
styles instead of using `StringLiteralFlags::default()`. The remaining
snapshot changes are intentional and should preserve the quotes from the
input strings.

## Test Plan

Existing tests with some accepted updates, plus a few new RUF055 tests
for raw strings.
