[binder] Disable header in Parcel (#27229)

Java side implementation does not use header, so we need
AIBinder_Class_disableInterfaceTokenHeader to disable header.

The weak symbol will be resolved when the libbinder_ndk.so on device is
new enough. Otherwise, our transport implementation will keep using
header.

After SDK and NDK that support API level 32 get released, we will remove
this workaround and specify correct minSDKVersion in AndroidManifest
