Revert "Reland "Remove placeholder Obj-C headers and use angle-bracketed headers.""

This reverts commit 37d41eea047799ccca2f09c941870c26ee3ffc0a.

Reason for revert: Sorry for the back and forth here. I need to revert again because I need to fix a downstream project. The re-landing should
be without changes.

Original change's description:
> Reland "Remove placeholder Obj-C headers and use angle-bracketed headers."
>
> This is a reland of 6bfad33fd866e682c871c2ef2172b70b609593d1
>
> Original change's description:
> > Remove placeholder Obj-C headers and use angle-bracketed headers.
> >
> > sdk/objc/Framework/Headers are just a placeholder headers
> > for backward compatibility and I don't think it is really need this for now.
> > Instead, we can generate the framework header in
> > ios/mac_framework_bundle_with_umbrella_header.
> > Also clang supports the -Wquoted-include-in-framework-header warning,
> > and in Xcode 12, it's in Xcode's recommended settings. This warnings
> > can be avoided by replacing double-quoted includes with angle-bracketed
> > includes when generate framework headers.
