[zircon_benchmarks] Bench fdio_spawn instead of zx_process_create

Remove the process creation benchmark from perf-test and replace it
with an fdio_spawn benchmark.

Why remove the process creation benchmark? It relied on a launchpad
function that's about to become private,
launchpad_create_with_process.

$ /pkgfs/packages/zircon_benchmarks/0/test/zircon_benchmarks -p --filter=Fdio/Spawn
[ RUN      ] Fdio/Spawn
[       OK ] Fdio/Spawn
