Run solana checks via github actions

The current approach of running solana checks in Tilt is a bit unwieldy
and makes it hard to find errors in all the log spam.  Move the checks
into a github action instead.  This gives us more flexibility to add
formatting and linting checks and also makes it easier to quickly find
any issues in the logs.
