axi_window_remap

Remap AXI addresses inside one alias window onto a target base.

Addresses in [local_alias_base_i, local_alias_base_i + region_size_i) rewrite to target_base_i plus the offset; all others pass through unchanged. Only AW and AR addresses change, the module is combinational, and all window parameters are runtime inputs. The remap supports both local-alias and global-to-local remapping.

For example, local_alias_base 0xC000_0000, target_base 0x1000_0000 and region_size 0x50000 map 0xC000_1234 to 0x1000_1234 and leave 0x2000_0000 unchanged.
