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.

When an import is added to the ast, the import declarations are merged
together into the first import declaration. Since this is a part of
the formatting functionality of goimports, do this during formatting
regardless.
The merging pass was added to astutil.AddNamedImport in order to address
issue golang/go#14075. This joined imports from other blocks into the first
import declaration, so that a single block of imports isn't split across
multiple blocks.
This functionality is more of a formatting change than a fix imports
change, in line with sorting the imports, which occurs even when
FormatOnly. The formatting was only applied when an import was added
(not renamed or deleted). This change makes formatting by goimports
more consistent across runs and is not dependent on the exact fixes
that need to be applied.

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.
