Packages found in the module cache do not change. When we encounter a
directory we have already processed in the module cache, skip that
directory and add the packages that have already been computed.

To check if a package is in a module that is in scope, the module
resolver checks if there are Go files that would be included in a
package in the directory matching the import path in scope.
If this directory is in the module cache and we have saved it as a
package, we know this directory contains Go files, and do not have to
read the directory.

The root of the module containing a package in the module cache can be
determined by looking at the directory path. Use this instead of
scanning up the file tree to find the mod file of a package from a
module cache. The go command prunes nested modules before populating
the module cache, so there is only one go.mod within each module.

The module cache can only be added to, so any information discovered
about directories that are within a module in the module cache will
not change. Store the information we have discovered about the module
cache.

Have the imports resolvers load the exports for packages. This allows
each resolver to provide its own implementation of loading exports,
beyond reading from the directory.

Save the packages found when scanning of the module cache.
The computed package may have a different import path due
to replace directives, so this needs to be updated
when the moduleResolver is initialized again.

The imports ProcessEnv contains cached module and filesystem state. This change
allows gopls to use the same ProcessEnv and resolver across multiple calls to the
internal/imports library.
A ProcessEnv belongs to a view, because the cached module state depends
on the module that is open in the workspace.
Since we do not yet track whether the 'go.mod' file has changed, we
conservatively reset the cached state in the module resolver before
every call to imports.Process.

This change modifies gopls to use the internal goimports library, which
allows us to manually configure the ProcessEnv. We also add a logger to
the ProcessEnv to allow this change not to conflict with gopls's logging
mechanism.

For various reasons we need an internal-facing imports API. Move imports
to internal/imports, leaving behind a small wrapper package. The wrapper
package captures the globals at time of call into the options struct.
Also converts the last goimports tests to use the test helpers, and
fixes go/packages in module mode to work with empty modules, which was
necessary to get those last tests converted.
