[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.
