[feature request] proto as toolchain plugin

[harlequin]

At the moment we are able to define the proto version in moon via the toolchains.yml.

The complete handling is implemented in moon itself.

It would really great if proto can be a toolchain plugin because with this we would have some more possiblities

1. With an option we can define that all tools listed inside the .prototools shall be installed during the moon sync workspace stage
   Because at the moment only tools from a toolchain tier 3 will be installed automaticlly.

2. Or if the moon workspace sync can not be supported, due to toolchain detection we are able to create a common proto.yml inside the .moon/tasks folder which than can install the tools.

What do you think about this idea?
I can contribute this part.

I have plans for supporting proto install in moon, but it's a bit complicated. Will need to land changes in proto first.

For me as an intermediate solution which would work

create a toolchain plugin with manifest configuration to .prototools

during sync_workspace or sync_project execute the proto install command

Additional, for my use case I would likely to implement the proto status into the extend_task and extend_scripts to have the product_dir as concated list within the task as env variable.

Do you think when I would implement this for myself and use it, it would be future prove with your ideas?

The way I imagine it working would be a bit different. There will probably be another action in the graph specifically for it.
