[PATCH v8 00/16] Add a plugin to check Ecc issues for edk2 on open ci

["Zhang, Shenglei" <shenglei.zhang@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2606
As planed we will enable Ecc check for edk2 on open ci. And they are
ready now. I appreciate receiving feedback and comments if someone
find errors or false positive issues.

I created a pipline of EccCheck for my forked edk2. Welcome everyone to
create pull request to test the quality of this plugin.
My forked tree: https://github.com/shenglei10/edk2

And I also created some test cases for ECC plugin. Below are test cases.

Results can be view in below azure server.

Patches
1/16: It's a lib necessary for py3 to run Ecc on azure servers.

2/16: EccCheck.py is a plugin to report Ecc issues for commits. It can be run
     on azure servers for open ci, or a local virtual environment.

3/16~16/16: We consider some cases that will report out Ecc issues but they won't
     be fixed, like submodule and industry standard related things. So we
     add two configuration fields "Exception" and "IgnoreFiles" for people
     to use. These patches add configuration in yaml files for Ecc check.

v2: Update 1/17, fix the bug that the script can't hanlde multiple commits.

v3: Update 1/17, set the only workalbe workspace is edk2 root directory.
    Update 2/17, designate the version of antlr4 is 4.7.1.
    Add 4/17~17/17.

v4. Update 1/17, remove the function EdksetupRebuild(), instead add
    function SetupEnvironment(). Update variables' format and type hints
    to pass flake8 and mypy.

v5. Conver the former method to plugin solution, to align with
    other check points on open ci.

v6. The 1/16 patch is missed in v5 series. Now add it in v6.

v7. Fix a bug that Ecc plugin can not be run correctly under Linux OS.

v8. Enable error code config section to ignore certain kinds of issues,
    which are always false positive in partial Ecc scaning.
    All patches except 2/16 have been R-B and are not updated in v8 series.
    To avoid making noise in community, I only send cover letter and 2/16 patch.
