VDI reports the limits in pixels, but user provides the size in bytes.
Make sure both values are in pixels before doing comparisons.

Even though the runtime and driver texture object API is one to one, the structs used by these APIs are not. See hipResourceDesc vs HIP_RESOURCE_DESC differences.
These differences are not trivial and most likely won't be able to handled by hipify, so we need new API entry points.

This also adds declarations of all the missing texture APIs.
hipTexRefSet*() functions need to take a textureReference as a ptr for type erasure to work. Runtime has been modified to accomodate this.
This change only applies to VDI.

Instead of using the sampler field force_degamma to perform sRGB->linear conversion during pixel sampling, we use an appropriate image format instead. The overhead of this is having to create an image view when creating a texture object from an array.

All we have to do is align the ptr to HW requirments an if it's not zero, then return the offset to the user.
We currently don't have anywhere to store this offset, so hipGetTextureAlignmentOffset() will still always return 0.

Currently we extract the read mode from the ihip*impl() calls, which is not correct. We should be getting it from the texture itself directly.

If a user passes a ptr that was allocated by hipMalloc(), the offset is guaranteed to be 0 and NULL may be passed as the offset parameter. We shouldn't return an error in this case.

The current texture implementation is based off the one for HIP-HCC. There's a lot of problems with it - only creating images from buffers, hard coding logic and ignoring user parameters. This leads to a whole lot of UB even with simple examples (as seen with RedShift's code).
This CL is aimed to bring the HIP-VDI texture implementation closer to what is described by Cuda.
hipMemcpyAtoA() - image to image copy.
hipMemcpyHtoA()/hipMemcpyDtoA() - buffer to image copy.
hipMemcpyAtoH()/hipMemcpyAtoD() - image to buffer copy.
hipArrayCreate()/hipArray3DCreate()/hipMallocArray()/hipMalloc3DArray() - creates 1D/2D/3D/1D Array/2D Array images.
hipCreateTextureObject() - creates sampler, (optional) creates 1D/2D image from buffer, (optional) creates image views.
hipBindTexture() - creates 1D image from buffer (should create a typed buffer, however this is not compatible with HIP-HCC).
hipBindTexture2D() - creates 2D image form buffer.
hipBindTextureToArray() - creates image view.
hipTexRefSetAddress() - creates 1D image from buffer (should create a typed buffer, however this is not compatible with HIP-HCC).
hipTexRefSetAddress2D() - creates 2D image from buffer.
hipTexRefSetArray() - creates image view.
There are still a lot of TODOs in the code, here's a few important ones:
1. VDI doesn't support a lot of sampler flags.
2. VDI doesn't support device to image 2D/3D copy.
3. Mipmaps implementation is incomplete.
4. Image view implementation is incomplete.
