Rebecca Stambler a7c0594f4e internal/lsp: avoid logging context cancellation
This change adds a helper function that checks if the context is
canceled, and if so, doesn't log the error. Tried to use it everywhere
in internal/lsp where it fits, which resulted in changing a few pieces
of error handling throughout.

Updates golang/go#37875
