qiulaidongfeng 83a6c13e73 cmd/dist: avoid CPU underutilization starting from GOMAXPROCS=2 runtime 
This CL is doing now is:
change maxbg to increase test parallelism.
adjust test sequence.

This CL speeds up the go tool dist test,
most of the speed up is due to the fact that the
three time-consuming tests
cmd/internal/testdir and API check and runtime/race
can be done in parallel with the GOMAXPROCS=2 runtime
on a machine with enough CPU cores.

In windows with an 8-core 16-thread CPU,
this CL can complete all other tests before
GOMAXPROCS=2 runtime -cpu=1,2,4 -quick completes.

Fixes #65164
