feat: add new build.local.bazel entry for local, build-level Bazel configuration

[ar3s3ru]

Description
This PR adds a new configuration field in build.local specific to Bazel, to specify some build-level parameters for (or to pass to) Bazel.

Example usecase: passing --config=ci argument.

Before:

apiVersion: skaffold/v4beta6
kind: Config
build:
  artifacts:
    - image: hello
      bazel:
        target: //path/to:hello.tar
profiles:
  - name: ci
    patches:
      - op: add
        path: /build/artifacts/0/bazel/args
        value: [--config=ci]

After:

apiVersion: skaffold/v4beta6
kind: Config
build:
  artifacts:
    - image: hello
      bazel:
        target: //path/to:hello.tar
profiles:
  - name: ci
    build:
      local:
        bazel:
          args: [--config=ci]

Gentle ping @ericzzzzzzz @renzodavid9 could you take a look at your earliest convenience? 🙏🏻

hi @ar3s3ru sorry for the late review, but I think the existing behavior makes more sense , the bazel config should not be put under build environment stanza, it seems confusing to me why local build has this config, while other cluster, cloudbuild don't. This config is applying buildargs to bazel artifacts, it also seems to suggest that other builder should have corresponding config under local or cloudbuild stanza as well. Another thing is that, we also need to handle conflicts between this args configured through this stanza and those configured in bazel artifacts, should we do a merge or full replacement? Which should have higher priority? This will make things more complex, also ss you can basically achieve the same thing by a little bit repetitions, we probably don't need this change.
