[PATCH 0/5] Add a pipline 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, but these are V1 series. So I expect that contributors in
edk2 community can try using this script when reviewing. And I hope
receiving feedback and comments if someone find errors or false positive
issues.

I created a pipline of EccCheck for my forked edk2.

Patches
1/5: This is a patch to enable python 3.8 for Ecc. It is a tool issues not
     a pipline or script issue. But it is listed here for people willing
	 to try this tool.
2/5: EccCheck.py is a tool to report Ecc issues for commits. It can be run
     on azure servers for open ci, or locally. Its usage is like
	 PatchCheck.py.
3/5: It's a lib necessary for py3 to run Ecc on azure servers. For local
     use, we need to type command
	 "py -3 -m pip install antlr4-python3-runtime" first.
4/5: Windows-EccCheck.yml is a yaml file to configure the newly added
     pipline. The azure uses this to create a pipline.
5/5: 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. The patch is a example and the contents in the fields will be
	 empty in final version.

Note: For now this pipline can't report out Ecc issues like Tab character
      and trailing white spaceLine. And above issues are listed in CSV file
	  after Ecc scanning traget files. But PatchCheck.py can report out them.
	  I wonder whether we need to enable the above mentioned check
	  points in this pipline, becaue either pipline fails, the commit will not
	  be checked in.
