[cryptolib] Add support for cryptolib static library release target

[moidx]

Description

The cryptolib is currently built with the following target:

bazel build --platforms=@crt//platforms/riscv32:opentitan //sw/device/lib/crypto:otcrypto

Bazel however does not have support for generating static library binaries by default. There is an RFC proposing the addition of a cc_static_library being tracked in bazelbuild/bazel#1920 (see doc and gist).

This issue is to track the implementation of a static library target.
