The C preprocessor allows backslash-newline anywhere and allows
comments anywhere it allows space. Testing wilfully perverse
applications of that revealed qmake's parsing of #include directives
wasn't very robust. So rework to actually follow the rules and add
those tests.

Can't sensibly test unless the compiler does support raw strings,
since any test that would catch qmake's (prior) inability to parse raw
strings would necessarily confuse the C++ compiler in the same way.
This even applies (in test app code) to any #if-ery around the raw
string, since tokenization happens before preprocessor directives are
resolved. So the #if-ery on Q_COMPILER_RAW_STRINGS has to be in
tst_qmake.cpp, not the test app it builds.
