Add CLAMP operator to Dynamic Fusion interface
Add the CLAMP activation function for GPU backend with generic activation Component and TemplateWriter modules.
CLAMP is internally implemented as LU_BOUNDED_RELU activation function with the alpha and beta variables swapped.
We do NOT consider in-place computation cases in this patch.
* CLAMP operator for GPU backend.
* Activation Component and TemplateWriter for CL backend.
* TemplateWriter generates tiled kernel code.
* Supported data types: F16, F32.
* Validation tests for CLAMP operation.
