[yaml2obj][test] Move tests to binary format specific subdirectories

[MaskRay]

Summary

Create COFF/, ELF/, and Minidump and move tests there.

Also

• Rename *.test to *.yaml
• For yaml2obj RUN lines, use -o %t instead of > %t for consistency. We still have tests that check stdout is the default output, e.g. multi-doc.test
• Update tests to consistently use ## for comments. # is for RUN and CHECK lines.
• Merge symboless-relocation.yaml and invalid-symboless-relocation.yaml to ELF/relocation-implicit-symbol-index.test

Mostly looks fine to me.

Maybe add "in a symbol".

llvm/test/tools/yaml2obj/ELF/verdef-section.yaml

Delete "the".

llvm/test/tools/yaml2obj/ELF/verneed-section.yaml

1

Delete "the".

I might be misreading the intent of the comment, but I think there's value in testing:

Symbols:

distinctly from

Symbols: []

In other words, can yaml2obj handle it with/without the [].

We probably don't have other tests that check Symbols: with the value omitted now.

Added it back with a comment.

[grimar]

Nice cleanup! I've found only a single minor nit.

LGTM, with one suggestion.

This phrasing sounds a bit clunky to me. How about "... but here we show that the value can be omitted."
