* add gfx1100 support
Add support for Radeon 7900 GPUs (RX and PRO), and 7800 PRO.
I was contemplating to add gfx1101 and gfx1102 GPUs as well, but those are the lower end models that are more unlikely to be used for compute intensive jobs. In addition, I do not have access to them to test the support.
* update WF_SIZe for different options
Radeon systems use a WarpSize of 32, unlike current Instinct systems,
which use a warp size of 64. For the device side, a gfx specific ifdef
is sufficient. For the host side, we need to query the device
properties.
* adjust functional tests to wf_size of 32
* update unit tests to handle wf_size of 32
* address reviewer comments
