QEvdev: Extract Method parseSpecification()
All four manager classes contained roughly the same code in their
ctors that parsed out devices from a colon-separated string.
Extract shared code, and port the parsing to QStringRef (later to be
ported to QStringView).
Saves ~2.4KiB on optimized Linux GCC 9.1 AMD64 builds across all
.so's that link to libQtInputSupport.a.
