opt: make findImportMap async

[sigmaSd]

This is just a small optimization since it kind of annoyed me that this block while the importMap are supposed to run in parallel (for multiple entry-points).

The new lint can't catch this, because deno lints are purely syntax based.

Or maybe it can , with too much work, for example consider eaech function thave inside it a deno sync api a blocking function, and save it on a list and now each time we see it we also consider the parent blocking and so on, and now if we see one of these in an async context we emit a warning , that would be cool.

Interesting. Maybe we propose this to deno_lint...oh you already did 👍
denoland/deno_lint#1198

The change here sounds good anyways. Thanks, you're my ace.
