  [clang][bytecode] Support ObjC blocks (#104551)

I started out by adding a new pointer type for blocks, and I was fully
prepared to compile their AST to bytecode and later call them.

... then I found out that the current interpreter doesn't support
calling blocks at all. So we reuse `Function` to support sources other
than `FunctionDecl`s and classify `BlockPointerType` as `PT_FnPtr`.
