Split OSREPORT logging type

The enumerated LOG_TYPE "OSREPORT" is currently used in both EXI_DeviceIPL.cpp and HLE_OS.cpp.  In many games, the multitude of game functions detected by HLE_OS.cpp for OSREPORT logging results in poor log readability.  This Pull Request remedies that by adding a new enumerated LOG_TYPE "OSREPORT_HLE" for log usage in HLE_OS.cpp.

In the future, further changing how logging in HLE_OS.cpp works may be desirable.  As it is, game functions are detected that send a single character to the log.  This is a major source of poor readability.
