Upgrade go version to 1.16.4

[wjhuang2016]

Development Task

TiDB uses go version 1.13.4 currently. If we want to use the newer version, we need more tests for it.
We have better to discuss what tests we need in this issue.

I am not a mac user, but I expect users will soon want to build with go 1.16 because of the native M1 support.

@wjhuang2016 I'd suggest change the title name to Upgrade Go Version to 1.16 and thus we get it clear.

I know that @CadmusJiang and @zhouqiang-cl are in charge for upgrading Go Version to 1.16 and most of validation works are done manually. Hopefully we get it done in this month and I'd like to use this existing issue as a tracking issue.
