Summary: Update `OIGenerator` and out BUCK stuff for compile time OIL with OIL v2. Main things: - Switch `OIGenerator` from the `getObjectSize` call to the new `introspect` call. - Switch from looking at template parameters to looking at function parameters, as this was exposing a bug in our elfutils/drgn and this way it's the same as OID. - Migrate `OIGenerator` to CodeGen v2 and update CodeGen v2 to accept a linkage name. - Update the compile time example to be the same as the JIT example, using the new interface and the JSON exporter. - Clean up the `ObjectIntrospection.h` header.
