treewide: rework function memory model
- Instead of treating individual program functions as managed ucode types,
demote uc_function_t values to pointers into a uc_program_t entity
- Promote uc_program_t to a managed type
- Let uc_closure_t claim references to the owning program of the enclosed
uc_function_t
- Redefine public APIs uc_compile() and uc_vm_execute() APIs to return and
expect an uc_program_t object respectively
- Remove vallist indirection for function loading and let the compiler
emit the function id directly when producing function construction code
