Hard Feature Freeze starts now for edk2-stable202102


Hi, all

Today, we enter into Hard Feature Freeze phase until edk2-stable202102 tag
is created at 2021-03-05. In this phase, there is no feature to be pushed.
The critical bug fix is still allowed. So far, there are two patches to
catch this stable tag. They both passed code review before HFF. If no
objection, they will be merged for this stable tag.

1. Fix two issue in ArmGicLib

2. Fix CET shadow stack token busy bit clear issue

If the patch is sent after Hard Feature Freeze, and plans to catch this
stable tag, please add edk2-stable202102 key words in the patch title and
BZ, and also cc to Tianocore Stewards, then Stewards can give the comments.

Below is edk2-stable202102 tag planning.
