Backport upstream patches to support vIOMMU:

reverted patches that were previously merged from upstream. These patches were not completely backported from the original patch series, causing numerous conflicts during subsequent merges.
backported patches from upstream sequentially according to their commit order.
Test cases:

| Case  | ARM  | Intel | AMD  |
|---|---|---|---|
| Build and Boot   | Yes  | Yes  | Yes  |
|  Host FIO test with IOMMU enabled | Yes  |  Yes | Yes  |
| IOMMUFD selttest  |  Yes | Yes (with a knowed fix )  |  Yes (with a knowed fix ) |
|  SVA | / (No supported device)  | Yes (with DSA)  |  / (No supported device) |
