Fix build with ICC under IPO on Windows 

qmake.conf(25) incorrectly sets QMAKE_CFLAGS_DISABLE_LTCG to -Qno-ipo.
The correct form to disable IPO on Windows with ICC 18.x and 19.x should
be: -Qipo-. The implication is that the CONFIG feature in simd.prf (31)
modulating the compilation of specific ISA optimized sources now
successfully disables IPO on intel_icl when needed.

Fixes: QTBUG-78976
