 rust: offer the current version to macOS 10.12 Sierra

 Upstream supports x86_64-apple-darwin back to macOS 10.12, so there is no
 reason to hold Sierra at the frozen 1.78.0.  Confirmed that the upstream
 stage0 binaries actually run there: `otool -l` on the 1.96.0 stage0 rustc
 and
 cargo both report a 10.12 deployment target.  `rust_build.stage0_info`
 already
 routes mdt >= 10.12 to the "apple" vendor, so no MacPorts-built stage0 is
 needed and rust-bootstrap does not have to be rebuilt.

 Moves the freeze boundary from "10.12 and below" to "10.11 and below" in
 the
 four coupled conditions in lang/rust (version/revision, supported_archs,
 source
 checksum, cargo.crates) and in the two rust_build procs that key on the
 deployment target.  All four Portfile conditions must move together -- the
 source checksum one in particular, or Sierra would fetch the 1.97.1
 tarball and
 verify it against the 1.78.0 hash.

 10.12 is also dropped from the mirror_all_architectures deployment-target
 lists, since x86_64 there now uses the upstream stage0 and i386 is no
 longer a
 supported arch at 10.12.

 Note this does drop i386 on 10.12: the current branch is arm64/x86_64
 only.
 Upstream demoted 32-bit Apple targets to tier 3 in 1.42 and ships no i386
 artifacts, and there is no MacPorts i386 stage0 at 1.96.  Sierra i386
 users
 would need the frozen 1.78.0.

 Not yet build-tested on 10.12 itself.  The compiler path is the same one
 10.13
 uses -- Sierra's Apple clang is below the cxx_standard 2017 bound, so it
 falls
 back to MacPorts clang -- and 10.13 is green through 1.97.1.
