QSet: remove use of Q_OUTOFLINE_TEMPLATEHEADdev

This is a test balloon to check whether this is still neeeded. The
only currently-supported compiler for which this isn't defined to
nothing is MSVC, and I'm pretty sure we define members of template
classes out-of-body without this macro elsewhere. This author believes
that no such thing as an out-of-line template exists, because all
templates have inline linkage, and that merely the inline keyword was
missing in the declaration of the function.

Amends the start of the public history.

Picking back to current LTS + 1 to get some user coverage in.

Pick-to: 6.10 6.9
