/**
This function accepts a <MultiKeywordResp> formatted string, finds the associated
keyword owners, creates a <MultiConfigResp> string from it and forwards it to the
EFI_HII_ROUTING_PROTOCOL.RouteConfig function.
If there is an issue in resolving the contents of the KeywordString, then the
function returns an error and also sets the Progress and ProgressErr with the
appropriate information about where the issue occurred and additional data about
the nature of the issue.
In the case when KeywordString containing multiple keywords, when an EFI_NOT_FOUND
error is generated during processing the second or later keyword element, the system
storage associated with earlier keywords is not modified. All elements of the
KeywordString must successfully pass all tests for format and access prior to making
any modifications to storage.
In the case when EFI_DEVICE_ERROR is returned from the processing of a KeywordString
containing multiple keywords, the state of storage associated with earlier keywords
is undefined.
@param This Pointer to the EFI_KEYWORD_HANDLER _PROTOCOL instance.
@param KeywordString A null-terminated string in <MultiKeywordResp> format.
@param Progress On return, points to a character in the KeywordString.
Points to the string's NULL terminator if the request
was successful. Points to the most recent '&' before
the first failing string element if the request was
not successful.
@param ProgressErr If during the processing of the KeywordString there was
a failure, this parameter gives additional information
about the possible source of the problem. The various
errors are defined in "Related Definitions" below.
@retval EFI_SUCCESS The specified action was completed successfully.
@retval EFI_INVALID_PARAMETER One or more of the following are TRUE:
1. KeywordString is NULL.
2. Parsing of the KeywordString resulted in an
error. See Progress and ProgressErr for more data.
@retval EFI_NOT_FOUND An element of the KeywordString was not found.
See ProgressErr for more data.
@retval EFI_OUT_OF_RESOURCES Required system resources could not be allocated.
See ProgressErr for more data.
@retval EFI_ACCESS_DENIED The action violated system policy. See ProgressErr
for more data.
@retval EFI_DEVICE_ERROR An unexpected system error occurred. See ProgressErr
for more data.

This function accepts a <MultiKeywordRequest> formatted string, finds the underlying
keyword owners, creates a <MultiConfigRequest> string from it and forwards it to the
EFI_HII_ROUTING_PROTOCOL.ExtractConfig function.
If there is an issue in resolving the contents of the KeywordString, then the function
returns an EFI_INVALID_PARAMETER and also set the Progress and ProgressErr with the
appropriate information about where the issue occurred and additional data about the
nature of the issue.
In the case when KeywordString is NULL, or contains multiple keywords, or when
EFI_NOT_FOUND is generated while processing the keyword elements, the Results string
contains values returned for all keywords processed prior to the keyword generating the
error but no values for the keyword with error or any following keywords.
@param This Pointer to the EFI_KEYWORD_HANDLER _PROTOCOL instance.
@param NameSpaceId A null-terminated string containing the platform configuration
language to search through in the system. If a NULL is passed
in, then it is assumed that any platform configuration language
with the prefix of "x-UEFI-" are searched.
@param KeywordString A null-terminated string in <MultiKeywordRequest> format. If a
NULL is passed in the KeywordString field, all of the known
keywords in the system for the NameSpaceId specified are
returned in the Results field.
@param Progress On return, points to a character in the KeywordString. Points
to the string's NULL terminator if the request was successful.
Points to the most recent '&' before the first failing string
element if the request was not successful.
@param ProgressErr If during the processing of the KeywordString there was a
failure, this parameter gives additional information about the
possible source of the problem. See the definitions in SetData()
for valid value definitions.
@param Results A null-terminated string in <MultiKeywordResp> format is returned
which has all the values filled in for the keywords in the
KeywordString. This is a callee-allocated field, and must be freed
by the caller after being used.
@retval EFI_SUCCESS The specified action was completed successfully.
@retval EFI_INVALID_PARAMETER One or more of the following are TRUE:
1.Progress, ProgressErr, or Resuts is NULL.
2.Parsing of the KeywordString resulted in an error. See
