windows: Make solana-test-validator work (#20099)

* windows: Make solana-test-validator work

The important changes to get this going on Windows:

* ledger lock needs to be done on a file instead of the directory
* IPC service needs to use the Windows pipe naming scheme
* always disable the JIT
* file logging not possible yet because we can't redirect stderr,
but this will change once env_logger fixes the pipe output target!

* Integrate review feedback
