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 V3 series. So I expect that contributors in
edk2 community can try using this script when reviewing. And I appreciate
receiving feedback and comments if someone find errors or false positive
issues.

I created a pipline of EccCheck for my forked edk2.

Patches
1/17: 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.
2/17: 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==4.7.1" first.
3/17: Windows-EccCheck.yml is a yaml file to configure the newly added
     pipline. Azure uses this to create a pipline.
4/17~17/17: 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.
