feat(xds): named resources (listeners) builders require name

[mmorel-35]

Defines the listener name as a required field for the builder constructor function and adds a validation in the final build function to throw an error if the field is blank.
It defines a default name for inbound and outbound listeners, but a withName function allows to define a custom name.
It also removes the name assignation from several configurers. It asserts that the name shall be known when the builder is instantiated.

Checklist prior to review

• Link to relevant issue as well as docs and UI issues -- xDS generators should require resource names #2538
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? --
• Do you need to explicitly set a > Changelog: entry here or add a ci/ label to run fewer/more tests?

Few nits, but LGTM overall.

Re. WithName and WithOverwriteName I'm open to discussion, as I'm not strongly opinionated about it.
