dynamic_modules: promote HTTP filter dynamic modules to GA (#44420)

## Description

We are now promoting `envoy.filters.http.dynamic_modules` from alpha to
stable (GA). The HTTP filter has had substantial production burn time
and a stable ABI.

Security posture updated from `unknown` to
`requires_trusted_downstream_and_upstream`, consistent with all other
dynamic modules extensions. All other dynamic modules extensions remain
`alpha` for now.
