chore(tvix): move castore golang bindings to tvix/castore-go r/6843
Have `tvix/castore/protos` only contain the protos, no go noise.

Make the `.pb.go` file generation a pure Nix build
at `//tvix/castore/protos:go-bindings`, and have a script at
`//tvix:castore-go-generate` (TBD) that copies the results to
`tvix/castore-go`.

`//tvix:castore-go`, with sources in `tvix/castore-go` now contains the
tooling around the generated bindings, and the generated bindings
themselves (So go mod replace workflows still work).

An additional CI step is added from there to ensure idempotenty of
the .pb.go files.

The code.tvl.fyi webserver config is updated to the new source code
path. I'm still unsure if we want to also update the go.mod name. While
being a backwards-incompatible change, it'll probbaly make it easier
where to find these files, and the amount of external consumers is still
low enough.

Part of b/323.

+# castore-go
+
+This directory contains generated golang bindings, both for the `tvix-castore`
+data models, as well as the gRPC bindings.
+
+They are generated with `mg run //tvix:castore-go-generate`.
+These files end with `.pb.go`, and are ensured to be up to date by a CI check.
+
+Additionally, code useful when interacting with these data structures
+(ending just with `.go`) is provided.
