[ATfE] Enable all v7-M, v8-M, and v8.1-M variants for LLVM-libc tests (arm#478)

saturn691 · web-flow · commit a83e9dc64a4b · 2025-08-11T14:30:55.000+01:00
arm#420 introduced hermetic testing for LLVM-libc. However, it did not enable all variants. Now we enable all possible variants that compile, to prepare for use in pre-merge scripts.
