[yaml2obj][test] - Merge strtab-implicit-sections-*.yaml into strtab-implicit-sections.yaml and improve testing of .shstrtab
This creates `strtab-implicit-sections.yaml` and merges 2 `strtab-implicit-sections*` tests into it. I've also added a few tests for `.shstrtab` section related to section flags. With that we have a single place where we can test implicit string table sections and the `.shstrtab` section in particular. Differential revision: https://reviews.llvm.org/D90372
