[bazel,dvsim] enable passing `--data-perm` flag through dvsim/bazel

This enables passing the `--data-perm` flag of the `gen-otp-img.py`
script through dvsim and Bazel to allow setting this parameter for
top-level tests that make use of the Bazel-generated OTP image by
setting the `OtpTypeCustom` flag in the `chip_sim_cfg.hjson` file.

To use this flag, users must simply set the `BAZEL_OTP_DATA_PERM_FLAG`
environment variable on the dvsim run-stage machine (i.e., the machine
that invokes Bazel to build the top-level test SW images). This can be
done by setting environment variables in the `chip_sim_cfg.hjson` dvsim
config file directly using the `exports` list (see line 138).
