Move all examples to cpp-example-collection

[stephen-derosa]

Move all examples to cpp-example-collection repo.

Depends on:
livekit-examples/cpp-example-collection#4

[Copilot]

Pull request overview

This PR removes the in-repo examples/ tree and replaces it with a cpp-example-collection git submodule, integrating its build into the main SDK build when LIVEKIT_BUILD_EXAMPLES is enabled.

Changes:

• Deleted all existing examples/** sources and the examples/CMakeLists.txt build.
• Added a new cpp-example-collection submodule and a CMake integration helper to configure/build it.
• Updated top-level CMake and gitignore to support the new examples workflow.
