binder: convert logging macros into functions

binder: convert logging macros into functions

Converting binder_debug() and binder_user_error() macros into functions
reduces the overall object size by 16936 bytes when cross-compiled with
aarch64-linux-gnu-gcc 11.2.0:

$ size drivers/android/binder.o.{old,new}
   text	   data	    bss	    dec	    hex	filename
  77935	   6168	  20264	 104367	  197af	drivers/android/binder.o.old
  65551	   1616	  20264	  87431	  15587	drivers/android/binder.o.new

This is particularly beneficial to functions binder_transaction() and
binder_thread_write() which repeatedly use these macros and are both
part of the critical path for all binder transactions.

$ nm --size vmlinux.{old,new} |grep ' binder_transaction$'
0000000000002f60 t binder_transaction
0000000000002358 t binder_transaction

$ nm --size vmlinux.{old,new} |grep binder_thread_write
0000000000001c54 t binder_thread_write
00000000000014a8 t binder_thread_write
