go/build: move build constraint docs to 'go help buildconstraint'

CL 228017 added a new help page 'go help buildconstraint' which
summarized the information on build constraints in the go/build
documentation. The summary was almost as long as the go/build
documentation, since there's very little that can be left out.

This CL moves the original go/build documentation to
'go help buildconstraint' to eliminate redundnancy. The text
describing enabled tags is slightly different (targeting command-line
users more than go/build users), but the rest of the documentation is
unchanged.

Fixes #37018
