Replace the stub implementation of invalidation with the proper
implementation. A ReadPathCache is added to each global so that it can
keep tracks of what target are associated to which read paths.
This commit changes the following method names across the codebase:
* `storeToDisk` -> `store`
* `loadFromDisk` -> `load`
This has been done since the storage is no longer bound to the local
storage.

The misspelling on the argument description made the --help option very
unhelpful in discovering the proper usage of the tool.
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.
`DocumentError`s are the inteded way of propagating errors from the
pipeline to the frontend when a location is required to inform the user
of the error whereabouts.
FunctionMetadata was being deserialized every time they were
inspected. This commit introduces a cache structure to prevent this
excessive deserializations.
When revng-artifact is requested to produce the functions of a binary
that had 0 functions, it crashed. This commit fixes it by checking if
something has been actually being produced.
