Add Windows application manifest

The manifest contains four things:
- declare compatibility with Windows 10 & 11
  - we were running inside a Windows Vista compatibility context before
- set process DPI awareness to PerMonitorV2
  - this is already set by Qt programmatically at start up
- use v6 instead of v5 of the CommonControls library
  - enable modern styles in system dialogs
- user account control settings
  - for completeness. The linker adds that by default anyway, so this
    was already part of the executable
