Rebecca Stambler 3cbd95df51 internal/lsp: support a file belonging to multiple packages
This change adds supports for a package belonging to multiple files.
It requires additional packages.Loads for all of the packages to which a
file belongs (for example, if a non-test file also belongs to a package's
test variant).

For now, we re-run go/packages.Load for each file we open, regardless of
whether or not we already know about it.

This solves the issue of packages randomly belonging to a test or not.
Follow-up work needs to be done to support multiple packages in
references, rename, and diagnostics.

Fixes golang/go#32791
Fixes golang/go#30100
