cmake: bintools: gnu: Suppress GDB check console outputs

Browse source 
The GDB check routine added in the PR #38749 does not suppress the
console outputs (stdout and stderr) and may print out a misleading
error message during a CMake configuration when the required version
of Python is not available on the system:

  arm-zephyr-eabi-gdb: error while loading shared libraries:
  libpython3.8.so.1.0: cannot open shared object file: No such file or
  directory

This commit adds the `OUTPUT_QUIET` and `ERROR_QUIET` options when
executing the GDB process so that the console outputs during the GDB
executable validation are not displayed to the user.

In addition, this commit removes the unused `GDB_PY_NO_PY` standard
output redirection variable since it is unnecessary.
