/**
Extracts ASSERT() information from a status code structure.
Converts the status code specified by CodeType, Value, and Data to the ASSERT()
arguments specified by Filename, Description, and LineNumber. If CodeType is
an EFI_ERROR_CODE, and CodeType has a severity of EFI_ERROR_UNRECOVERED, and
Value has an operation mask of EFI_SW_EC_ILLEGAL_SOFTWARE_STATE, extract
Filename, Description, and LineNumber from the optional data area of the
status code buffer specified by Data. The optional data area of Data contains
a Null-terminated ASCII string for the FileName, followed by a Null-terminated
ASCII string for the Description, followed by a 32-bit LineNumber. If the
ASSERT() information could be extracted from Data, then return TRUE.
Otherwise, FALSE is returned.
If Data is NULL, then ASSERT().
If Filename is NULL, then ASSERT().
If Description is NULL, then ASSERT().
If LineNumber is NULL, then ASSERT().
@param CodeType The type of status code being converted.
@param Value The status code value being converted.
@param Data Pointer to status code data buffer.
@param Filename Pointer to the source file name that generated the ASSERT().
@param Description Pointer to the description of the ASSERT().
@param LineNumber Pointer to source line number that generated the ASSERT().
@retval TRUE The status code specified by CodeType, Value, and Data was
converted ASSERT() arguments specified by Filename, Description,
and LineNumber.
@retval FALSE The status code specified by CodeType, Value, and Data could
not be converted to ASSERT() arguments.
