Some scrollbars appear light in dark mode on ARM64

[derceg]

In #478, it was reported that the application was crashing when dark mode was enabled on ARM64. From investigation, the crash was triggered by an illegal instruction (0xc000001d) error, when calling OpenNcThemeData after installing a detour. It's possible that's due to a bug in the Detours library. Similar issues have been described in microsoft/Detours#276 and microsoft/Detours#292, for example.

As the detour has been disabled, the crash described in #478 no longer occurs. However, it means that some scrollbars (e.g. the listview scrollbar) will appear light when dark mode is enabled on ARM64.

Therefore, the detour should either be re-enabled, if this issue is fixed within the Detours library, or an alternative solution should be found.
