Symfony allows internal address and port enumeration by NoPrivateNetworkHttpClient
### Description
When using the `NoPrivateNetworkHttpClient`, some internal information is still leaking during host resolution, which leads to possible IP/port enumeration.
### Resolution
The `NoPrivateNetworkHttpClient` now filters blocked IPs earlier to prevent such leaks.

The second one is available [here](https://github.com/symfony/symfony/commit/b4bf5afdbdcb2fd03da513ee03beeabeb551e5fa) for branch 5.4 also.
