fix(MeshHTTPRoute): only configure HTTP outbounds or with an explicit matching rule

[michaelbeaumont]

Closes: #6860

Checklist prior to review

• Link to relevant issue as well as docs and UI issues -- Confusion with MeshHTTPRoute configuring listeners with httpConnectionManager for every outbound #6860
• 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?

@michaelbeaumont I allow myself to merge it, as I want to make sure MeshTCPRoute works as expected with your changes (ref. #6873)
