[ty] Add `ty.configuration` and `ty.configurationFile` options

[MichaReiser]

Summary

This PR adds two new LSP settings:

• configuration: Inline configuration similar to ty check --config. Allows setting configurations in addition to what's configured in the project
• configurationFile: A path to a ty.toml configuration file to use instead of any auto-discovered configuration

Fixes https://github.com/astral-sh/ty/issues/786

Fixes https://github.com/astral-sh/ty/issues/1084, although I think we probably want to have dedicated editor toggles for some settings because editing the inline JSON is no fun.

Known limitations

Relative paths in the ty.toml file will be relative to the workspace root, which might be surprising if the feature is used in a case as described in https://github.com/astral-sh/ty/issues/2034 where the project is in a sub-directory.

I think the proper solution for https://github.com/astral-sh/ty/issues/2034 simply is better mono-repository support or supporting workspace-folders.

Test Plan

Added E2E tests
