refactor(oxfmt): Migrate all tests to JS based (#15285)

Previously, `oxfmt`'s e2e tests were written in Rust.
However, after migrating our CLI to napi, e2e tests using Vitest were also added.

As a result, there is no longer any reason to maintain tests on the Rust side.
Additionally, while tests using `napi` are possible in Vitest, they are not possible in Rust.

So consolidated everything to Vitest.

Additionally, I added tests that were not included in the previous PR for `embeddedLanguageFormatting: "auto" | "off"`.
