lsp: cache swc ASTs

[dsherret]

I'm breaking this out of #11032

Also, caching the swc parse of the module in the document info would be a good thing I think. That might take a bit more structuring of code. It is used in dependency analysis of the document as well as the test code lens and also use by the linting (though I don't know how easy it would be to send it to deno_lint without a bigger refactor of one or the other).

Steps:

• Remove use of SourceMap and SourceFile in the code because they don't implement Send without turning on swc_common's concurrent feature, which is not something I want to do because then all the code will use locks internally (which we don't need... slower), open us up to a new class of possible bugs, and it's a global change.
  • refactor: remove SourceMap dependency from dep-graph swc-project/swc#1908 - Remove SourceMap dependency in swc dep-graph and integrate into Deno code
  • Add replacement functionality for SourceMap/SourceFile's BytePos -> Line and column that exists on ParsedModule.
  • Do as many parts of Change AST analysis code to use only indexes rather than both indexes and line and columns #11111 as makes sense for completing this task (probably using what's implemented on ParsedModule in the step above might make most of this not required to complete this task)
  • Refactor code for transpiling and bundling to still use SourceMap & SourceFile as it is required by swc, but change the rest of the code not to use that.
• Replace SingleThreadedComments implementation of Comments with a version that implements Send.
• Store the ParsedModule in the document cache and use it throughout the code.
