This splits the validation code from parsing code, potentially allowing
us to either fully deferring it to the daemon, or to perform validation
separately.
For reference; daemon-side validation currently (docker 29.2.0) produces;
docker run --rm --mount type=bind,src=/var/run,target=/foo,bind-recursive=writable alpine
docker: Error response from daemon: mount options conflict: !ReadOnly && BindOptions.ReadOnlyNonRecursive
docker run --rm --mount type=bind,src=/var/run,target=/foo,bind-recursive=readonly alpine
docker: Error response from daemon: mount options conflict: !ReadOnly && BindOptions.ReadOnlyForceRecursive
Validation for BindOptions.Propagation is currently missing on the daemon;
docker run --rm --mount type=bind,src=/var/run,target=/foo,bind-recursive=readonly,readonly alpine
# no error
