Rollup merge of #56913 - tirr-c:uefi-stack-probes, r=alexcrichton
Enable stack probes for UEFI images When building UEFI images, we don't link to any CRT libraries so we need to provide a stack probe. Without `__rust_probestack`, the linker looks for `__chkstk` and fails to link if there is a function with large local variables. r? @alexcrichton
