MdeModulePkg: DxeReportStatusCodeLib: Do not query protocol
This commit stops the library from querying the protocol database for
the status code protocol at the time of library function use. This logic
can result in a TPL inversion if the protocol has not yet been cached
and the caller is calling the library function when the TPL is higher
then TPL_NOTIFY.
Instead, the protocol is now located during the constructor of the
library. If the protocol is not found, then an on-protocol install event
is registered which will cache the protocol. A destructor is also added
to close the event in the scenario that the driver is unloaded before
the protocol is installed.

MdeModulePkg: Add unit tests for DxeReportStatusCodeLib
This commit adds a host based unit test for DxeReportStatusCodeLib
that ensures that the platform cannot invert the TPL on an initial
call to ReportStatusCode functionality.
