[Backport 1.28] Fixed bazel configuration ambiguity for non HTTP3 builds (#34483)

[tedjpoole]

Back port of #34483 to release/v1.28.

To avoid ambiguity when building with //bazel:http3=False (on PPC and Windows) this commit adds new config_setting_groups and updates the relevant select() statements.

I've done #34966 for 1.29 but have no need for 1.27

@phlax will this merge once the release/v1.28 branch is reopened, or is there something else I need to do?

@tedjpoole apologies i should have landed this before we released - seems like this backport is gtg - i hadnt due to the ci failure on other branch/es

[tedjpoole]

@phlax No worries about missing the release. I can cherry pick it for now thanks
