gopls/internal/govulncheck: add in-memory cache for vulndb

We used govulncheck.DefaultCache that is a cache in file system.
This helps clients from hitting the network excessively.
Mod diagnostic is computed very frequently, however, even file
read & unmarshal contents for every module for every diagnostic
computation can become slow. This CL adds an additional layer of
caching that holds the information in memory. To avoid network
access across gopls restarts, this cache is backed by the file
system cache where the cached data is persisted on disk.
