add support for arm64 architecture for watchOS devices (Xcode 14)

[aleksandergrzyb]

Description of the feature request:

Xcode 14 adds arm64 architecture for watchOS devices:

Currently Bazel only supports armv7k and arm64_32.

When you would like to build for watchOS device using arm64 architecture (watchOS_arm64) currently it will get incorrectly mapped to watchOS simulator which already supports arm64 architecture.

I've already submitted PR (#16181) with proposed changes:

• Adds watchos_arm64 to supported watchOS device architectures.
• Renames watchos_arm64 to watchos_sim_arm64 (following the convention as for tvOS and iOS).

What underlying problem are you trying to solve with this feature?

I would like to build in Xcode 14 for watchOS devices with arm64 architecture.

Which operating system are you running Bazel on?

macOS Monterey 12.5.1

What is the output of bazel info release?

release 5.3.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.
