internal/lsp: use the explicit import spec name as ident

When there is an explicit name for an import spec, treat it as its own
identifier, separate from the import path.

Example:
	import h "hello"

The name h is defined in that import spec, not in the package hello
it contains its own references. If asked about a position within the
import path, continue treating that as referencing the imported package.
If the position is within the name, use the identifier there that is
local to that file.

This change allows for go to definition of the explicit name to point to
itself, find all references from the import spec, and rename the
explicit name from the import spec.
