* Source/WTF/wtf/SHA1.h:
Recent SDK changes resulted in CoreUtils headers getting imported into
translation units (MediaPlayerPrivateWebM.mm) that also import `SHA1.h`.

The aforementioned CoreUtils headers have long had a macro SHA1(),
which conflict with our template functions' definitions, and make SHA1.h
fail to parse.

As a quick workaround, undefine the rogue macros before our SHA1 class.
