Do not do any logging initialization when logging is disabled

Reviewed by Simon Fraser.

Source/WebCore:

Initializating of the logging channels was taking time on startup. When logging is disabled
(and the LOG macro does nothing), we should aslo disable logging channels and initialization.

This patch #ifdef the Logging initialization with the macro LOG_DISABLED.

* WebCore.exp.in:
* make-export-file-generator: Explicitely adds Assertions.h so that LOG_DISABLED is defined.
