fd/decode: Build generate_rd executable rather

Browse Source 
A seperate meson project with mesa as a subproject was required to
compile the generate_rd executable for replaying rddecompiler
generated source. That approach was overly complicated, now the
generate_rd executable is now compiled as a part of building the
freedreno tools with a blank generate-rd.cc file that can be replaced
with the source generated by rddecompiler.
