[roll] Roll fuchsia [build][fidl] Clean up experimental flags
This CL adds experimental flag forwarding to the GN SDK
gen_fidl_response_file.py script; makes it and the internal
gen_response_file.py use --experimental rather than --experimental-flag
for consistency with fidlc; and removes the obsolete new_syntax_only
flag so that we can delete it from fidlc.
Forwarding experimental flags in the GN SDK script is important so that
we can enable flags in the out-of-tree repo along with any necessary
code changes, rather than unconditionally setting flags in the script
and having to rely on LSC presubmits.
