Allow 'features' customization via 'user_options' (#192)

'features' provides a mechanism for customizing the Bazel toolchain
configuration:

docs.bazel.build/versions/main/cc-toolchain-config-reference.html

It's a useful knob to expose via PodToBUILD for those cases when you
want a library to opt-in to features like dead code stripping, dsym
generation, or other local toolchain features.

Revert "Stop setting -DNS_BLOCK_ASSERTIONS=1 for :release (#194)

for build environments that expected this to be set due to customized
cc_toolchains, so let's revert it for now.

platforms (which is what :release uses):

headermap generation rule.
