Rollup merge of #130741 - mrkajetanp:detect-b16b16, r=Amanieu
rustc_target: Add sme-b16b16 as an explicit aarch64 target feature LLVM 20 split out what used to be called b16b16 and correspond to aarch64 FEAT_SVE_B16B16 into sve-b16b16 and sme-b16b16. Add sme-b16b16 as an explicit feature and update the codegen accordingly. Resolves https://github.com/rust-lang/rust/pull/129894.
