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
