xrt-smi code cleanup

[aktondak]

Problem solved by the commit

This PR is a code re-organizationa and cleanup. No new functional logic has been implementation/changed. Following are the changes made :

• The shared SMI types/implementation moved out of flat core/common/smi.{h,cpp} into a dedicated core/common/smi/ tree with separate Alveo, and Ryzen pieces.
• This PR also consolidates different copies of shim implementations into just 2 Alveo and Ryzen pieces, with core_common_smi_objects (plus core_smi_alveo_objects / core_smi_ryzen_objects) so xrt_coreutil and the right shims link the right object files instead of xdna/mcdm maintining their own source. This is done since we do not see a lot of difference between xrt-smi ryzen specific implementation on windows vs. linux, thus it makes sense for both to have common code. On similar lines, pcie and edge also now share a common config generation logic (smi_alveo.cpp/.h).
• Platform-specific blobs smi_pcie, smi_edge, and the driver’s smi_xdna and smi_mcdm were removed(code change in XDNA and MCDM repos respectively) in favor of the shared headers/APIs and the Ryzen implementation under core/common/smi/.

The build currently fails as there there is an xdp dependency on smi.h which is failing due to path change. I've opened an xdp PR for this and will update the xdp submodule in XRT once reviews on this PR are done.
