API / ABI break in 0.3.64: PW_KEY_NODE_TARGET no longer defined (at least in header files)

I'm co-maintaining the PipeWire Rust bindings on Fedora, and they started to fail to build since the update to PipeWire 0.3.64 with this error:

error[E0425]: cannot find value `PW_KEY_NODE_TARGET` in crate `pw_sys`

It might not break the ABI if this constant is still there but just not exported in header files, but it's still a breaking change. The release highlights for 0.3.64 mention that the NODE_TARGET has been deprecated (but not that it has been removed).
