UEFITool / UEFIExtract / UEFIFind NE A66

Changes:

• New guids command for UEFIExtract and an update to default extraction modes to include generation of known GUID database (pairs of GUID/String that can be collected from the input file), thanks to @NikolajSchlej.
• Update to Qt 6.5.0 (LTS) brough seamless cross-platform UI dark mode support, and proper handling of UI mode update, thanks to @NikolajSchlej.
• QHexEdit2 widget replaced by QHexView5 for Hex View window. The new widget looks nicer in HiDPI and natively supports dark UI mode. Thanks to @Dax89 for creating it and @NikolajSchlej for integration work.

Fixes:

• lots of small fixes for issues found by fuzzing, thanks to @yeggor and @NikolajSchlej
• small update to built-in GUID database, thanks to @Tody-Guo
