/**
A temparaty function that returns the size of a Null-terminated Unicode
string in bytes, including the Null terminator.
This function returns the size, in bytes, of the Null-terminated Unicode
string specified by String. It duplicates the functionality of StrSize()
in MDE library, but avoids using PCD, because IPF currently cannot convert
address of global variable for runtime.
If String is NULL, then ASSERT().
If String is not aligned on a 16-bit boundary, then ASSERT().
@param String Pointer to a Null-terminated Unicode string.
@return The size of String.
