Add operator<< support to RTCError

Replace the internal `std::string` message storage in `RTCError` with
`StringBuilder`. This enables the use of streaming operators to append
details to error messages directly.

Introduce a `LOG_ERROR()` helper as a more C++ like alternative to the
`LOG_AND_RETURN_ERROR` macro. This allows for cleaner C++ syntax with a
visible return statement, such as:

return LOG_ERROR(RTCError(...) << "Error details");`

Also introducing a static construction helper to RTCError for the
commonly used INVALID_PARAMETER error type, InvalidParameter(). This is
the same approach as is currently used with the OK() construction
helper.
