api: remove [:alpha] protodoc tag and replace with annotation (#18218)

This is a first step towards https://github.com/envoyproxy/envoy/issues/17920

A single proto (kafka mesh) has been swapped from using the udpa
file_status annotation to the xds file_status annotation to avoid a
large amount of churn and a forthcoming migration of many alpha/wip
protos to non alpha/wip. The rest will be audited and swapped in
future PRs. This single one was done to make sure the doc machinary
works properly.
