doc: Remove explicit support for mips64el-linux.
It's been a good run, but no one is maintaining the architecture. So long, and thanks for all the fish. * doc/guix.texi (GNU Distribution): Change text for mips64el-linux to denote it is deprecated. (Daemon Offload Setup): Change occurrences of mips64el-linux to aarch64-linux and adjust local code snippets. (Guix Environment)[cross-compilation]: Change mips64el-linux-gnu to aarch64-linux-gnu. (GNU Build System)(package-cross-derivation]: Same. (G-Expressions)[cross compilation]: Same. (Additional Build Options)[cross-compilation, build logs]: Same. (qemu-binfmt-service-type): Remove mips64el. * doc/contributing.texi (Submitting Patches): Same. * m4/guix.m4: (GUIX_ASSERT_SUPPORTED_SYSTEM): Remove mips64el-linux.
