Auto merge of #82838 - Amanieu:rustdoc_asm, r=nagisa
Allow rustdoc to handle asm! of foreign architectures This allows rustdoc to process code containing `asm!` for architectures other than the current one. Since this never reaches codegen, we just replace target-specific registers and register classes with a dummy one. Fixes #82869
