Add hip::syncStreams(dev) to sync blocking streams on a given device.
hip::syncStreams(void) should only sync streams on the current device.

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.

Also make D2H and H2D keep track of the chain of events
when we need to use a different HostQueue.

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.

Review comments - generate hiprtc lib everytime when HIP_PLATFORM is hcc
Changes for hip-clang
Removing pre processor directive to simplify

The current implementation of surd2D{read/write} directly addresses into
the image buffer via the hipArray::data ptr. This is incorrect to do
since we don't know the layout of the image. Also with VDI we won't have
access to the underlying image buffer.
Disable the surface api untill the device functions are switched to
using __ockl_image_{load/store}().

Make __gnu_h2f_ieee and __gnu_f2h_ieee visible so that hipTestHalf
test can succeed in Clang compiler + Hcc RT.

And also don't optimize the case where start==stop event to compute
elapsed time since the command can be a NDRange one.
HIP directed test will need to be fixed for that.
