SWDEV-273235 - Initial support for Windows CMake

This change is tied to the ROCclr cmake rework. ROCclr will now be built
as part of HIP itself.

All the dependencies on comgr and rocr have been moved into ROCclr
itself. This allows HIP to pull in all the required compiler/runtime
dependencies by simply linking against ROCclr. Note that ROCclr needs to
be configured from HIP cmake command line. If not, we will default to
LC + ROCr support.

Since HIP depends on ROCclr and ROCclr depends on OpenCL, HIP will
transitevly pull in all the required OpenCL headers. No need to keep a
local copy of them anymore.
