 go_toolchain-1.0.tcl: new PortGroup for versioned Go toolchains

 Records which Go releases upstream supports on which versions of macOS,
 and
 builds versioned go-1.NN toolchain ports.

 The table of minimum darwin versions is the single source of truth; the
 ceiling
 for a given system and whether a minimum can be satisfied there are both
 derived from it, so that the toolchain a system installs and any future
 floor
 enforced on Go ports cannot disagree. Including the PortGroup has no side
 effects, so it can be included purely to consult the table.

 These are hard runtime limits rather than build limits. From Go 1.25 the
 darwin
 runtime resolves Security.framework symbols such as
 _SecTrustCopyCertificateChain via //go:cgo_import_dynamic even with CGO
 disabled, so a too-new Go aborts under dyld regardless of how it was
 produced.
 The 1.25 binaries are the first to carry that undefined symbol, and the
 first
 built with a minimum of macOS 12.
