chore: code format check

[luohoufu]

What does this PR do

code format check

Rationale for this change

This pull request includes several changes to the .github/workflows/pr-check.yml file to add a new job for format checking and modifies some existing job configurations. Additionally, it removes some constants from the config/generated.go file.

Workflow improvements:

• .github/workflows/pr-check.yml: Added a new format_check job that includes steps for setting up the Go toolchain, running make format, and checking for changes after formatting. If changes are detected, the workflow will fail.
• .github/workflows/pr-check.yml: Removed the fetch-depth parameter from the Checkout current repository, Checkout framework repository, and Checkout framework-vendor steps in the unit_test job.

Code cleanup:

• config/generated.go: Removed unused constants LastCommitLog, BuildDate, EOLDate, Version, and BuildNumber.

Standards checklist

The CI part looks good to me, but I am not sure about the .gitignore part because I am not familiar with the runtime files that Loadgen would generate so I will leave it up to @medcl
