Some code lenses may be undesirable for certain users or editors -- for example a code lens that runs tests, when VSCode already supports this functionality outside of the LSP. To handle such situations, support configuring code lenses via a new 'codelens' gopls option. Add support for code lens in regtests, and use this to test the new configuration. To achieve this, thread through a new 'EditorConfig' type that configures the fake editor's LSP session. It made sense to move the test Env overlay onto this config object as well. While looking at them, document some types in source.Options.
