Stephan Bergmann 91ba9654ba Move tools/diagnose_ex.h to comphelper/diagnose_ex.hxx
...so that its TOOLS_WARN_EXCEPTION can be used in
comphelper/source/misc/logging.cxx in a follow-up commit.  (And while at it,
rename from diangose_ex.h to the more appropriate diagnose_ex.hxx.  The
comphelper module is sufficiently low-level for this immediate use case, so use
that at least for now; o3tl might be even more suitable but doesn't have a
Library until now.  Also, for the immediate use case it would have sufficed to
only break DbgGetCaughtException, exceptionToString, TOOLS_WARN_EXCEPTION,
TOOLS_WARN_EXCEPTION_IF, and TOOLS_INFO_EXCEPTION out of
include/tools/diagnose_ex.h into an additional new
include/comphelper/diagnose_ex.hxx, but its probably easier overall to just move
the complete include file as is.)
