[VP] Kill VP_PROPERTY_(MEMOP,CASTOP) and simplify _CONSTRAINEDFP [nfc] (#105574)
These lists are quite static. Heavy use of macros is undesirable, and not idiomatic in LLVM, so let's just use the naive switch cases. Note that the first two fields in the CONSTRAINEDFP property were utterly unused (aside from a C++ test). In the same vien as #105551. Once both changes have landed, we'll be left with _BINARYOP which needs a bit of additional untangling, and the actual opcode mappings.
