Fix compilation error when using Algorithm::setPushConstants(const std::vector<T> &)

[mitjap]

This function is templated and is never instantiated in kompute project so the compilation error was not detected.

When calling Algorithm::setPushConstants(const std::vector<T> &), this function then calls Algorithm::setPushConstants(void* data, uint32_t size, uint32_t memorySize) which accepts non-const pointer.

This PR adds a test that instantiates this function and validates the results and also fixes the incorrect function signature.
