OvmfPkg: Add OVMF Memory Debug Logging MemDebugLogLib library
Add the Memory Debug Logging feature MemDebugLogLib library
which provides the key MemDebugLogWrite() function.
Several versions (i.e. SEC, PEIM, DXE, runtime) of
the function are included to provide the proper
method to write the debug messages to the memory
debug log buffer.
The library also provides the core functions to maintain
the circular memory debug log buffer.
