Yaniv Michael Kaul b8a150e22c build: add -ftime-trace support for compilation profiling ...

Add a --time-trace flag to configure.py and a Scylla_TIME_TRACE CMake
option that enable Clang's -ftime-trace on all C++ compilations. When
enabled, each .o file produces a companion .json trace that can be
analyzed with ClangBuildAnalyzer or loaded in chrome://tracing to
identify slow headers and costly template instantiations.

This is the first step toward data-driven build speed improvements.

Usage:
  configure.py:  ./configure.py --time-trace --mode dev
  CMake:         cmake -DScylla_TIME_TRACE=ON -DCMAKE_BUILD_TYPE=Dev ..
