update grpc to 1.43 (ray-project#21866)

add patch for newer setuptools, can be removed once grpc 1.44 is release

Why are these changes needed?
With grpc updated to 1.43, one of the patches is not needed.

Patch needed when building locally for newer setuptools version. See grpc/grpc#28392 for more details.
Also needed as a prereq to ray-project#21221
