[Object/invalid.test] - Convert most of the sub tests to YAML.
Object/invalid.test is a test case that is used to check the behavior of tools when broken inputs are used. The most often tool tested there is llvm-readobj. I think we might want to move such tests to test\tools\llvm-readobj. For now this patch converts many sub-tests to use YAML and removes 12 binaries from the inputs.
