ci(*): deprecate github action jobs to prevent developer misunderstanding and interference

[wlwilliamx]

What problem does this PR solve?

Issue Number: close #12361

What is changed and how it works?

This PR completely removes the "Check & Build" GitHub Actions workflow by deleting the .github/workflows/check_and_build.yaml file.

Why is this change necessary?

The "Check & Build" workflow is a known source of instability and random failures. These failures often have no connection to the code changes being proposed in a pull request.

Crucially, these jobs are not required checks for merging a PR. However, their failure frequently confuses contributors, leading them to believe their PR is blocked. This creates unnecessary noise and requires developers to investigate non-critical issues.

By removing this workflow, we aim to:

• Eliminate a flaky and unstable CI process.
• Reduce confusion for developers during the PR process.
• Save CI resources that were being used on these non-essential builds.

What has been changed?

The file .github/workflows/check_and_build.yaml has been deleted. This action removes the following CI jobs that were previously triggered on pull requests and pushes to master and release branches:

1. docker_build: This job ran on ubuntu-latest and executed the following steps:

   • docker build -f ./deployments/ticdc/docker/Dockerfile .
   • docker build -f ./dm/Dockerfile .
   • docker build -f ./deployments/engine/docker/Dockerfile .

2. mac_build: This job ran on macos-latest and was responsible for:

   • Setting up the Go v1.23 environment.
   • Running make build.
   • Running make check.

3. arm_build: This job ran on a self-hosted ARM64 runner and was responsible for:

   • Setting up the Go v1.23 environment.
   • Running make build.

The removal of the file also gets rid of the workflow's trigger conditions and concurrency settings.
