Consolidate API of target_supports_multi_process

This simple commit consolidates the API of
target_supports_multi_process.  Since both GDB and gdbserver use the
same function prototype, all that was needed was to move create this
prototype on gdb/target/target.h and turn the macros declared on
gdb/{,gdbserver/}target.h into actual functions.

Regtested (clean pass) on the BuildBot.
