This commit bans from the model array types in as argument or return
types in CABIFunctionDefinition.
CABIFunctionDefinition implies we're decompiling towards C, and C does
not support array arguments (passed by copy) nor array return types.
Banning these from the model reduces the number of situations where we
have to emit artificial array wrappers (not present in the model) around
types when printing C code, simplifying the handling of such situations
when translating to clift and in general in the decompilation pipeline.
Here we start restructuring the the schemas YAML such that it
contains a top-level `version` field. In this commit we only modify
the YAML, the build system changes will come later, to avoid
enormous commits.
These schema files are currently generated at build time by
collecting various TUPLE-TREE-YAML comments using the
`extract_yaml.py` script. In this commit we move them to the codebase
but we don't use them yet, this will be done at a later commit for
the sake of readability.
