gopls/internal/lsp/cache: disable strict analysis while we fix panics

We now understand the longstanding race causing panics in gopls analysis
(the cache key for analysis handles is not correct, and can lead to
cache hits for analysis of stale packages).

It will take a little while to redesign our analysis caching, the
simplest solution being to hang analysis results off of the actual
package they are analyzing. In the meantime, suppress the panic as
before, to eliminate flakes.
