Syntactic compatibility for Python bindings v5 -> v6 #2852
Description
The rename from ARM64 to AArch64, and SYSZ to SYSTEMZ is annoying to do for Python bindings users. While v5 and v6 are NOT compatible due to many other improvements, the transition for users should be as smooth as possible.
This requires some similar solution like the compatibility header we have for C code.
Something plug & play style, which makes all the syntactic issues go away. So users can focus solely on the semantic changes.
It should be fully generated and tested.
