cmd/go: consolidate fuzz-support checks

We had been repeating conditions for specific platforms and
architectures to gate fuzzing tests, but the more of those tests we
add the more we will have to update if the set of supported platforms
and archictures expands over time.

We also ought to provide a friendlier error message when
'go test -fuzz' is used on non-supported platforms.

This change adds predicates in cmd/internal/sys, which already
contains similar predicates for related functionality (such as the
race detector), and uses those predicates in 'go test' and TestScript.

For #48495
