The code for formatting function signatures is fairly confusing.
Factoring out an unexported signature type simplifies things a bit.
Hopefully we'll be able to pull out more formatting logic from the other
features. Ideally, I'd like to return to the separation between
internal/lsp/source and internal/lsp so that a formatting package can be
pulled out and used in internal/lsp.

This change does not complete the work to handle snapshots correctly,
but it does implement the behavior of re-building the snapshot on each
file invalidation.
It also moves to the approach of caching the FileHandles on the snapshot,
rather than in the goFile object, which is now not necessary.
Finally, this change shifts the logic of metadata invalidation into the
content invalidation step, so there is less logic to decide if we should
re-load a package or not.
