feat(tools/tvlc): init project

Browse source 
tvlc is a tool for managing sparse git worktrees of the TVL depot.
It is still in development; near-term tasks include a setup script,
Nix dependency resolution, worktree removal, and the dispatch
script.

See cs.tvl.fyi/depot/docs/designs/SPARSE_CHECKOUTS.md for more info.
