fix: Update dfu-util to 0.11 on Windows and Linux

[geosmall]

Summary

Update dfu-util to version 0.11 on all platforms for consistent DfuSe support.

Windows Fix (Critical)

The previous Windows dfu-util.exe (version 0.1+svn from 2007-2008) lacked DfuSe support. The -s/--dfuse-address flag is required for STM32 DFU uploads.

Error on Windows:

dfu-util.exe: invalid option -- s

Linux Update

The Linux binaries were also outdated (x86_64 was version 0.8 from 2014).

Changes

Windows

• Update win/dfu-util.exe to 0.11 static build (self-contained, no DLL dependencies)
• Remove unused Cygwin DLLs (cygwin1.dll, cygiconv-2.dll) - ~2.9MB reduction
• Remove unused libusb0.dll (old libusb-0.1, not used by dfu-util 0.11)

Linux

• Update linux/x86_64/dfu-util from 0.8 to 0.11
• Update linux/x86_64/dfu-prefix and dfu-suffix to 0.11
• Update linux/aarch64/dfu-util, dfu-prefix, dfu-suffix to 0.11

Result

All platforms now consistent at dfu-util 0.11:

Platform	Before	After
Windows	0.1+svn (2007)	0.11
Linux x86_64	0.8 (2014)	0.11
Linux aarch64	unknown	0.11
macOS	0.11	0.11 (unchanged)
