If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.
Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

This change ports the functionality of https://github.com/sqs/goreturns
to be used as code actions on diagnostics that have missing
return values. It improves on the original goreturns functionality by:
- filling out empty return statements
- trying to match existing return values to the required return
values and then filling in missing parameters

This change removes the disabledAnalyses setting and replaces it with a more general feature named "analyses". This will allow users to opt in as well as opt out of analyzers that they do not find useful. This also updates some documentation to show users what analyzers gopls is using and which are enabled by default.
