GetPrerequisites.cmake : Exclude delay load dependencies under windows

Pascal Thomet requested to merge pthomet/cmake:get_prerequisites_delayload2 into master

This commit tries to solve the issue : #16241 (closed)

See comment made by l0calh05t in this thread: "I just had a look into GetPrerequisites.cmake, and on windows either dumpbin (MSVC) or objdump (MinGW) are used. Interesting fact: objdump doesn't even list the delay loaded dependencies, so to get consistent behavior between the two they should always be ignored."

l0calh05t was worried that the message "Image has the following delay load dependencies" might be localized on different Windows languages. Based on my experiences ("Windows 7 french" and "Windows Server 2008 R2" hosts), it is not translated (at least in french).

Below is an example output (AUHOR_WARNING) with Qt5WebEngineCore.dll:
