Remove the deprecated functionalities scheduled to be removed in Nx v21.
BREAKING CHANGE: Remove the deprecated data persistence operators
previously exported in `@nx/angular` and the deprecated testing utils
previously exported in `@nx/angular/testing`.
## Current Behavior
The logic for the `module-federation-dev-server` and
`module-federation-ssr-dev-server` is duplicated across Angular, React
and Rspack.
The majority of this logic is the same, and the duplication causes an
increased maintenance tax.
## Expected Behavior
Move the logic into a utility that is exposed from
`@nx/module-federation`.

Fixes#26169
## Current Behavior
The configuration of the served MFE always passed to the remotes. If a
new configuration is needed to skip one remote (e.g.
`serve:skip-remote1`) but `remote2` then a configuration called
`skip-remote1` is needed in the `remote2`.
## Expected Behavior
Add an ability to override the configuration and the empty
configurations in the remotes can be deleted.
