Generate all the benchmarks to run.

Instead of requiring the need to maintain a list of all the benchmarks,
add a programmatic way to generate all of the benchmarks.

This generation runs the benchmarks in alphabetical order.

Add a new macro BIONIC_BENCHMARK_WITH_ARG that will be the default argument
to pass to the benchmark. Change the benchmarks that require default arguments.

Add a small example xml file, and remove the full.xml/host.xml files.

Update readme.

Test: Ran new unit tests, verified all tests are added.
