Summary [CMake] Adds checks for execinfo.h and backtrace[_symbols]

Instead of relying on a set of preprocessor checks to determine whether the execinfo.h header and the backtrace/backtrace_symbols functions are available, it would be better to detect this with CMake. The plan would be to: - Check whether <execinfo.h> is present. - Check whether the backtrace() function can be linked, either from libc, or from libexecinfo (some systems provide it there) - Define PAS_HAVE_BACKTRACE and HAVE_BACKTRACE accordingly. - Change the guards in libpas and WTF to PAS_HAVE(BACKTRACE) and HAVE(BACKTRACE) accordingly.
