qmake: it's impossible to configure some compiler and linker options in the generated vcxproj

My complaint is specifically about MSBuild project generation (vcxproj). The attached qmake project demonstrates issues #1 and #2.

1. Impossible to set /LTCG:INCREMENTAL, instead you get /LTCG
2. Impossible to set /DEBUG:FULL, instead you get /DEBUG
At the same time, options like /OPT:REF and /DEBUG:FASTLINK do work, so it's not a problem of processing options with semicilons. I assume qmake simply parses these particular linker options incorrectly.

3. Impossible to get rid of the /FC flag. For me it's just a cosmetic issue of log files being cluttered with unnecessary full paths, but more importantly, this option makes builds non-reproducible (since your binary depends on which folder the project was built from).
Detailed and simple to understand description of the problem with /FC and how to get rid of it here - CMake had the same issue and they fixed it: https://gitlab.kitware.com/cmake/cmake/-/issues/18261
