feat: expose table trait (#2097)

Similar to
c269524b2f
this PR reworks and exposes an internal trait (this time
`TableInternal`) to be a public trait. These two PRs together should
make it possible for others to integrate LanceDB on top of other
catalogs.

This PR also adds a basic `TableProvider` implementation for tables,
although some work still needs to be done here (pushdown not yet
enabled).
