Let openmax_dl remove assembler_debug_dir config; minor other tweaks.

I want to add a new flag passed to assembly invocations, but since openmax_dl
still doesn't use clang's integrated assembler (https://crbug.com/917355), it
needs to opt out of the new flag.

While here, also move the -fno-integrated-as into its own config that
doesn't get added to public_configs.

Also run `gn format` on the build file, which moved a few things around a bit.
