BR: Git action improvement

[fengou1]

What problem does this PR solve?

Issue Number: close #29622

Problem Summary:
currently, the runner quota only had 20 runner, those have to run all PR around 158 repo under PingCap. BR Git Action taken 30 minutes for each commit. We remote those redundant compile action, and trigger window compile only PR merged.

What is changed and how it works?

Remove compile under linux familiy kernel, BR only requires go to build project.
So that we remove MAC OS, FreeBSD and Ubuntu, only keep window platform, and only merge PR will trigger the Windows compile action.

• The "Ubuntu" one is actually building against AArch64
• The FreeBSD one was introduced in FreeBSD support br#1070 because it was found that FreeBSD's types are not exactly compatible with Linux.

These are still valuable. I'd suggest, based on https://github.community/t/trigger-action-via-pull-request-message/17630/4:

1. change the pull_request trigger to run only when a label was added:

   on:
     push:
       ...
     pull_request:
       types: [labeled]  # <--
       branches:
         ...

2. make the jobs conditional, only run when the label added is action/run-br-cross-platform-build .

   jobs:
     compile-windows:
       if: github.event_name == 'push' || github.event_name == 'pull_request' && github.event.label.name == 'action/run-br-cross-platform-build'
       ...
     compile-freebsd:
       if: github.event_name == 'pull_request' && github.event.label.name == 'action/run-br-cross-platform-build'
       ...
     compile-linux-aarch64:
       if: github.event_name == 'pull_request' && github.event.label.name == 'action/run-br-cross-platform-build'
       ...
     compile-macos:
       if: github.event_name == 'pull_request' && github.event.label.name == 'action/run-br-cross-platform-build'
       ...
