add action for cpp_infer build

[GreatV]

This pull request introduces a new GitHub Actions workflow for building and testing C++ inference code across multiple operating systems. The workflow is designed to work on Ubuntu, macOS, and Windows, and it includes steps for setting up dependencies, caching libraries, building the project, and running tests.

Key changes include:

New GitHub Actions Workflow:

• Added a new workflow file .github/workflows/cpp_infer.yml for C++ inference build and test. This workflow triggers on pushes and pull requests to the master and main branches, as well as manual dispatch.

Environment Setup:

• Defined environment variables for build type and OpenCV version.
• Configured matrix strategy to run jobs on ubuntu-latest, macos-latest, and windows-latest with specific URLs for downloading dependencies.

Dependency Installation:

• Added steps to install necessary dependencies for each operating system:
  • For Ubuntu: build-essential, cmake, libgoogle-glog-dev, libgflags-dev, libprotobuf-dev, and protobuf-compiler.
  • For macOS: cmake, protobuf, gflags, and glog via Homebrew.
  • For Windows: cmake,
