Restructure some tests to split into `%.test` and Inputs/%.c*`. Add test actions with `yaml2obj` for single byte coverage. `FileCheck` lines are: - Relax to accept both counter values and single values `1`. A few line counting are greater than `1` due to `llvm-profdata merge`. They will be fixed by #110972. - Suppress matching with `--check-prefixes=CHECK,BRCOV`, since the current implementation of single byte doesn't emit any branch coverages. They will be integrated to `CHECK` finally. - Some tests are not unified but use dedicated `CHECK` lines for single byte, since old format is different (esp. "partial fold"). They will be unified when `Inputs` will be regenerated. Introduce llvm/test/tools/llvm-cov/Inputs/yaml.makefile for convenience. `%-single.yaml` and `%-single.proftext` are generated by it. It could be used to regenerate other files. https://discourse.llvm.org/t/rfc-integrating-singlebytecoverage-with-branch-coverage/82492
