Updates to the build-file generation script.

This change adds ‘android-standalone’ and ‘bazel’ targets to the
build-file generation script. It also allows multiple build outputs to
be written in one invocation, which saves the cost of Perl to build all
the assembly files multiple times.

Note that this will require changes to the Chromium GYP files when its
rolled out because “boringssl_lib_sources” has been broken into
“boringssl_crypto_sources” and “boringssl_ssl_sources”.
