feat(imports): support import attributes - fixes #14674

[matthewp]

Description

Fixes #14674

Adds support for import attributes by parsing them in the import analysis plugin.

Additional context

How this works:

• es-module-lexer provides information about where the attributes are. We already use this to clip them off.
• We grab the string, which is an object literal { foo: 'bar' }
• We use Acorn to parse this string.
• Iterate over the AST to extract the values into an object
• Pass this through to resolveId where plugins can do what they want.

I'm not sure why this is failing in CI, likely a race condition some how. I'll take a look.
