Update on "[ET-VK] Introduce generalized shaders for transfer ops and use it for select and slice"

## Changes

* Introduce `transfer_buffer.glsl` and `transfer_texture.glsl`, and `Transfer.cpp` which generalizes shaders where each element of the output is copied from a unique element of the input.
* Update `Slice.cpp` and `Select.cpp` to use `Transfer.cpp`
* Remove old implementations of slice and select

## Motivation

With this new implementation, the op can now support both buffers and textures of any packing. There are also benefits of code consolidation.
