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.

We don't program the numChannels and format members (these are HCC specific), so printing these will only display garbage.

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.

The hipExtModuleLaunchKernel and hipModuleLoadDataMultiThreaded tests keeps randomly failing on Jenkins.

SWDEV-227875: Add a lock in streams to lock when the callback is call so we make sure things aren't moving forward in the stream
What Cuda refers to "linear texture memory" is the OpenCL equivalent of CL_MEM_OBJECT_IMAGE1D_BUFFER. For these types of allocations we should create a typed buffer instead of an image.
Currently there is no check in the texture fetch functions as to what kind of SRD is written into the texture object, so any kind of incorrect programming will cause the TA to hang. Fortunately for us, every one writes correct code :)

Currently the texture C++ API is forwarded to the ihip*Impl() calls, which are not even a part of Cuda. These should be forwarded to their respective Cuda C APIs instead.
This change also fixes a bug with hipUnbindTexture() creating a dangling pointer.

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.

reinterpret_cast<> doesn't create an object, so the texref is actually unitiliazed. This may lead to garbage data in some of its struct members.
Initialize it by performing a placement new. The constructer should set all of its members to default values. There's no way currently to extract the channel type, so use single channel char for now.

Similar to the previous patch, this change adds type constraints to texture indirect functions. Since we don't have to deduce the return type for these, we simply just have to check if the user provided a valid channel type.

When sampling a pixel the hw always returns a float4. The type in the texture reference controls the bitcast that we perform before returning the sampled pixel. Creating a texture with an unsupported will lead to potential UB.
This change makes it so that it's only possible to use textures with a type that makes sense. Using something like texture<int, hipTextureType1D, hipReadModeNormalizedFloat> will now lead to a compilation error with a message "Invalid channel type!".

This change addresses three things.
First the available APIs are brought up to par with Cuda (missing ones are added and incorrect ones removed).
Second the size of hip/hcc_detail/texture_functions.h. Using some template magic we can bring down the code size down from ~11k lines to only ~900 lines in total.
Third this change fixes some bugs in the declaration of the texture fetch funcitons. Currently the return type for textures with read mode set to hipReadModeNormalizedFloat is not float. This causes pixel data to be lost during the bitcast when the texture pixel element size is less than the size of float.
The new headers will only be enabled for VDI to avoid breaking HCC.

This is currently so buggy that it causes a runtime crash on Nvidia platfrom...
Disable the new version for hcc and vdi, header fixes are required for it to pass.
Currently tex1D<char, hipTextureType1D, hipReadModeNormalizedFloat> returns a char, when the actual sampled pixel value is a float, so the hi 3 bytes get lost.
