[EXT_EXP_BindlessImages] Create sampled image from a sampler object

[wenju-he]

Add a new descriptor ze_sampler_exp_desc_t that contains a pointer to sampler object. A bindless sampled image could be created by passing the new descriptor via pNext member using zeImageCreate API. Motivation is to support a single 64-bit handle for SYCL bindless sampled image.

There are two options hgow we can describe sampler for Sampled Image:

1. using one API call to create Sampled image : <redacted>-GSD-8290

// Define sampler ze_sampler_desc_t samplerDesc; samplerDesc.addressMode = ZE_SAMPLER_ADDRESS_MODE_CLAMP;

        ze_image_bindless_exp_desc_t bindlessExtDesc = {};
        bindlessExtDesc.stype = ZE_STRUCTURE_TYPE_BINDLESS_IMAGE_EXP_DESC;
        bindlessExtDesc.pNext = &samplerDesc;

// Indicate we allocate bindless SampledImage bindlessExtDesc.flags = ZE_IMAGE_BINDLESS_EXP_FLAG_BINDLESS | ZE_IMAGE_BINDLESS_EXP_FLAG_SAMPLED_IMAGE;

        ze_image_desc_t srcImgDesc = {ZE_STRUCTURE_TYPE_IMAGE_DESC,
                                      &bindlessExtDesc,
                                      0,
                                      ZE_IMAGE_TYPE_2D,
                                      {ZE_IMAGE_FORMAT_LAYOUT_8_8_8_8, ZE_IMAGE_FORMAT_TYPE_SINT,
                                       ZE_IMAGE_FORMAT_SWIZZLE_R, ZE_IMAGE_FORMAT_SWIZZLE_G,
                                       ZE_IMAGE_FORMAT_SWIZZLE_B, ZE_IMAGE_FORMAT_SWIZZLE_A},
                                      imageWidth,
                                      static_cast<uint32_t>(imageHeight),
                                      static_cast<uint32_t>(imageDepth),
                                      0,
                                      0};

        ze_image_handle_t srcImg = nullptr;
        SUCCESS_OR_TERMINATE(zeImageCreate(context, device, &srcImgDesc, &srcImg));

2. Create Sampler independently and attach existing sampler to image

Sampler may be used beofre image is created - passed as kernel argument - so it will need to have bindless slot allocated for Bindless addressing kernels

Then , when bindless sampled image is created - we would need to allocate sampler binldess slot again - rigth after image bindless slot.

I think for Sampled Images - it is better to allocate everything in one call - there is no need of tracking objects lifetimes in the app.
