Add support for tracing onto the PipelineC. This is done by: 1. Creating wrapper functions for each PipelineC function with the script in `scripts/PipelineC_add_tracing.py`. These will call a special function called `wrap` which will ultimately call a method with a `_` prepended to the name 2. Conversion of all PipelineC methods in `PipelineC.cpp` to `static` and their rename with a `_` in front, in order for them to work with the wrapper function in (1) 3. Generation of 2 additional include files, one for types and one for functions, to be used by users of tracing files in order to have introspection. These steps allow the creation of a trace file with the use of the `REVNG_C_API_TRACE_PATH` environment variable. The traces can then be used in conjunction with the `revng trace run` and `revng trace inspect` commands.
