CMake: Add an option to override cmake reader type

Add an option to override the cmake reader type that is going to
be used.

By default the reader type is "auto" for autodetection, but that can
get changed in the cmaketools.xml settings file. Other supported options
are "tealeaf", "servermode" or "fileapi" and that will force that reader.

You can also set QTC_CMAKE_IGNORE_FILEAPI=1 in your environment to force
creator to ignore the existence of fileapi support in all cmake tools.
