qcompilerdetection.h: add Q_COMPILER_UNIFORM_INIT
Up to now, the feature classe Uniform Initialization was subsumed by the Q_COMPILER_INITIALIZER_LISTS flag together with support for std::initializer_list. This caused at least two problems: 1. On QNX, the standard libray does not ship <initializer_list>, even though the compiler (a GCC 4.6, IIRC) supports it. But since there was only one Q_COMPILER flag for both, support for the compiler-only part of the feature had to be disabled, too. 2. MSVC 2013 supports initializer lists, but has a bug that renders full uniform initialization support, as required for QUuid, useless. By splitting the feature into two, we can separate them better, and do so in QUuid, which is the only class that currently takes advantage of uniform initialization (to provide constexpr constructors). Since Q_COMPILER_INITIALIZER_LISTS worked as a flag for uniform initialization so far, with the two known exceptions above, UNIFORM_INIT is defined whenever INITIALIZER_LIST is, except that I don't revert UNIFORM_INIT on QNX as I do for INITIALIZER_LISTS and that I expect the MSVC 2013 features to set INITIALIZER_LIST, but not UNIFORM_INIT.
