/*++
Routine Description:
This function extracts a string from a package already registered with the EFI HII database.
Arguments:
This - A pointer to the EFI_HII_PROTOCOL instance.
Handle - The HII handle on which the string resides.
Token - The string token assigned to the string.
Raw - If TRUE, the string is returned unedited in the internal storage format described
above. If false, the string returned is edited by replacing <cr> with <space>
and by removing special characters such as the <wide> prefix.
LanguageString - Pointer to a NULL-terminated string containing a single ISO 639-2 language
identifier, indicating the language to print. If the LanguageString is empty (starts
with a NULL), the default system language will be used to determine the language.
BufferLength - Length of the StringBuffer. If the status reports that the buffer width is too
small, this parameter is filled with the length of the buffer needed.
StringBuffer - The buffer designed to receive the characters in the string. Type EFI_STRING is
defined in String.
Returns:
EFI_INVALID_PARAMETER - If input parameter is invalid.
EFI_BUFFER_TOO_SMALL - If the *BufferLength is too small.
EFI_SUCCESS - Operation is successful.
