Remove patches and patchMad.sh

[Qubitol]

Implement the patches already in the code:

• either already in upstream code (for driver.f and matrix file);
• or in CUDACPP code (for makefile).

For the makefile in particular, I used an overlay approach, in which I put the patches inside an additional cudacpp_overlay.mk file, and modified the compilation commands in this way:

make -f makefile -f cudacpp_overlay.mk ...

so that the second file imported would override any recipe defined in makefile.

Instead of implementing the additions in upstream, use code generation and string placeholders in iolibs/template_files/madevent_driver.f, so that the changes are managed by the plugin itself, through overriding of write_driver in FortranExporterBridge.
Placeholders are called: CUDACPP_EXTRA_HEADER, CUDACPP_EXTRA_INITIALISE, CUDACPP_EXTRA_FINALISE.
