feat(BREAKING): drop the deno_ast dependency (#810)

This crate only used `deno_ast` for parsing and its parse diagnostics — everything else it needed already came from dprint-swc-ext, which `deno_ast` re-exports. It now parses with swc directly and owns its diagnostics, dropping 17 crates from the dependency graph.

A `deno_ast` user can still hand over an already parsed AST with its comments via dprint-swc-ext's `ProgramInfoProvider` trait, so nothing has to be parsed twice.

Breaking changes:

- `format_parsed_source` takes `FormatParsedSourceOptions` and is generic over `ProgramInfoProvider`, so it accepts a parsed source from any crate. It no longer checks the parse diagnostics, since it can't for a source it didn't parse — `parse_program` does that instead, and `is_unsupported_syntax_error` is public for callers that parse elsewhere.
- The formatting entrypoints take the swc `Syntax` the file was parsed with rather than a media type.
- `format_text` takes the file text as an `Arc<str>`.

Diagnostic messages are unchanged.
