* Bazel Platforms: Add `//cpu:any` constraint value for arch-indep builds
Some builds are expected to only produce architecture-independent data files,
such as configuration files, database seed data, composited images, or even
some kinds of interpreted scripts (Shell, Python, Perl, etc).
When such a build is being performed, this constraint value may be used to
ensure that architecture-dependent builds cannot be performed (except by way
of another transition).
As a final example, consider building a package of NIC firmware images for
many different NIC models. The package overall is architecture-independent,
and should be built with `//cpu:any`, then each individual image rule has a
transition to the suitable architecture for that specific NIC model.
* Update BUILD
Changed "any" to "all"

We intend to use this contraint for cpu & compiler selection for the
OpenTitan project. We are working on creating a riscv32 compiler
configuration in the bazel-embedded project.

On Apple silicon Macs, auto-detected host platform constraints' cpu is
aarch64, but arm64 is used everywhere else. This change ensures that you
will get the same cpu when your target depends on an arm64 or an aarch64
cpu contraint.
This is commonly known thumbv6. However, it appears that the name
is split between armv6-m and thumbv6 globally. I choose the arm
notation in order to be consistent with the other arm platforms.
