Utils: Add logging category to SynchronousProcess

This helps to debug e.g. runGcc(), which is used for detecting
predefined macros or header paths for the code model.

The log gives also a (limited) overview of the (blocking) processes that
are run on Qt Creator start up.

The produced command line is copy-pastable.

The generated output looks like this:

  qtc.utils.synchronousprocess: Starting blocking: /usr/bin/x86_64-linux-gnu-gcc-8 -dumpmachine
  qtc.utils.synchronousprocess: SynchronousProcessResponse: result=0 ex=0
  17 bytes stdout, stderr=""

  qtc.utils.synchronousprocess: Starting blocking: /usr/lib/icecc/bin/clang++ -x c++ -E -dM -
  qtc.utils.synchronousprocess: SynchronousProcessResponse: result=1 ex=115
  0 bytes stdout, stderr="ICECC[9867] 2019-07-03 13:00:35: couldn't find any clang++\nICECC[9867] 2019-07-03 13:00:35: could not find clang++ in PATH.\n"

  "The command \"/usr/lib/icecc/bin/clang++\" terminated with exit code 115."
