Set shorter build dirs for Qt Kits on Windows

Qt Creator creates build directories based on kit name and build configuration. Ás we have rather descriptive kit names, they can be quite long, i.e.g

 Boot2Qt_6_8_0_NVIDIA_Jetson_Orin_Nano_Developer_Kit-Debug

This is a problem especially on Windows, as the build path is showing up in command lines, and might cause commands to fail due to too long file names.

Instead of using the display name of the kit, Qt Creator allows setting a custom build name though. This can be achieved by setting a 'PE.Profile.FileSystemFriendlyName' when registering the kit via sdktool:

sdktool.exe addKit --id embedded.b2qt.680.jetsonorinnanodevkit.toolchain [...] "PE.Profile.FileSystemFriendlyName" "QString:B2Qt_6_8_0_JetsonOrinNano"
