internal/lsp: cache the imports ProcessEnv across imports calls

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.
