modfile: add support for go and toolchain lines

As part of the forward compatibility work, a new toolchain line
is being added, and go lines are allowed to specify toolchain
versions like "1.21.0" or "1.21rc1" now. (The lax RE has allowed this for quite
some time; what's new here is allowing it in the main module.)

For golang/go#57001.
