Rob Findley aa94e735be internal/lsp/source: add a new symbolStyle configuration option
Add a symbolStyle configuration option, and use it to parameterize the
following behavior when computing workspace symbols:

 + package (default): include package name in the workspace symbol.
 + full: fully qualify the symbol by import path
 + dynamic: use as the symbol the shortest suffix of the full path that
   contains the match.

To implement this, expose package name in the source.Package interface.
To be consistent with other handling in the cache package, define a new
cache.packageName named string type, to avoid confusion with packageID
or packagePath (if confusing those two identifiers was a problem, surely
it is a potential problem for package name as well).
