Run clang-format on Core

This copies over formatting changes from the Widevine CDM repository
that resulted from running clang-format with Google style on the
shared core/ directory. It also copies over some rewordings of log
messages that were made at the same time.

Aside from the changed log messages, this should not affect behavior
or functionality.
