QTestlib: Enable comparing QList against initializer lists/arrays

It is unnecessary to create a QList container just for comparison.

Split out helpers for comparing sequence sizes and sequences from
qCompare(QList) and add a template for an array with a non-type template
parameter for the size.

One can then write something like:

const int expected[] = {10, 12,...};
QCOMPARE(QFontDatabase.pointSizes(...), expected)

Unfortunately, any commas in such an array will be misread by macro expansion
as macro argument separators, so any expected array with more than one entry
needs an extra macro expanding __VA_ARGS__.
