[21660] Add flow_control, rtps, custom_payload_pool and content_filter to windows example ci testing

[Mario-DL]

Description

This PR adds the flow_control, rtps, custom_payload_pool and content_filter to windows example ci testing.
In particular, it

• Adds the required infrastructure to include environment args splitting them to be recognized as different argv in windows.
• Includes a new matched argument to the rtps example to wait for discovery before publishing.
• Adds a new argument samples to the subscriber content filter as a finish condition when it gets unmatched.

Note: In the content filter example the PUB_ARGS was removed since it was not being used in the compose file.

@Mergifyio backport 3.1.x 3.0.x
