chore: upgrade hidapi library to version 0.15

[creativeprojects]

Why this PR?

I tried to compile the project on my mac:
With the latest version of cmake from home-brew (cmake version 4.2.3) I wasn't able to compile the project with this error:

% cmake -G Ninja ..
CMake Deprecation Warning at CMakeLists.txt:19 (cmake_minimum_required):
  Compatibility with CMake < 3.10 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

CMake Error at external/hidapi/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

What is this PR doing?

• upgraded hidapi library from 0.14 to 0.15
• upgraded minimum required version of cmake

Testing

• happily running on my mac with a few hours of flight in x-plane 12.4
• not tested on windows/linux (don't have an x-plane license for those)

This PR vendors an updated hidapi (0.15.0) into the project to address build issues with newer CMake versions and to pick up upstream backend improvements across Windows/macOS/Linux/*BSD.

Changes:

• Upgrade vendored external/hidapi to 0.15.0, including new/updated public APIs (e.g., output report sending and read-error reporting).
• Update HIDAPI build/test assets (Windows descriptor reconstruction tests + new fixture data).
• Adjust CMake/autotools metadata/workflows inside the vendored HIDAPI tree.
