This adds an option WICKED_EMBED_SHADERS (off by default). When ON,
offlineshadercompiler will be compiled first and run every time
a *.hlsl? file changes, the resulting wiShaderDump.h will be put
in the build directory, and then wiRenderer will be compiled again with
the build directory in the include path; this will cause the
__hasinclude to trigger embedded shaders mode.
A nice side effect is that the hacky solution to handle the __hasinclude
is not needed anymore, all dependencies are now handled correctly.
offlineshadercompiler was also extended with a "quiet" option to
suppress messages during compilation.
Sanitizers added: address, undefined behaviour, thread
also rename WICKED_USE_{IPO,SYMLINKS} to WICKED_ENABLE_{IPO,SYMLINKS}
for consistency with the other options.
