[gq_ttq] add gq_ttq.mad to the repository

NB this has a single P1 subdirectory gq_ttxq! (but nprocesses=1 in each see madgraph5#272)

The Fortran code has DSIG1 and also DSIG2.
Clearly the DSIG2 code is not correctly interfaced to our cudacpp

The code fails to build:
...
ccache g++  -O3  -std=c++17 -I. -I../../src -I../../../../../tools -DUSE_NVTX -Wall -Wshadow -Wextra -ffast-math  -fopenmp -march=skylake-avx512 -mprefer-vector-width=256  -DMGONGPU_FPTYPE_DOUBLE -DMGONGPU_FPTYPE2_DOUBLE -I/usr/local/cuda-12.0/include/ -fPIC -c CPPProcess.cc -o CPPProcess.o
In file included from CPPProcess.cc:25:
coloramps.h:18:3: error: too many initializers for ‘const bool [5][4]’
   18 |   };
      |   ^
...
ccache /usr/local/cuda-12.0/bin/nvcc  -O3  -lineinfo -I. -I../../src -I../../../../../tools -I/usr/local/cuda-12.0/include/ -DUSE_NVTX -gencode arch=compute_70,code=compute_70 -gencode arch=compute_70,code=sm_70 -use_fast_math -std=c++17  -ccbin /usr/lib64/ccache/g++ -DMGONGPU_FPTYPE_DOUBLE -DMGONGPU_FPTYPE2_DOUBLE -Xcompiler -fPIC -c gCPPProcess.cu -o gCPPProcess.o
coloramps.h(13): error: too many initializer values

NB this is still using the old upstream mg5amcnlo before Olivier's split_nonidentical_grouping (see madgraph5#619)
I have previewed that after merging that, there will be two separate P1 subdirectories also in .mad (as in .sa)
