Returns an array of handles that support a specified protocol.
@paramin SearchType Specifies which handle(s) are to be returned.
@paramin Protocol Specifies the protocol to search by.
@paramin SearchKey Specifies the search key.
@param[in, out] BufferSize On input, the size in bytes of Buffer. On output, the size in bytes of
the array returned in Buffer (if the buffer was large enough) or the
size, in bytes, of the buffer needed to obtain the array (if the buffer was
not large enough).
@paramout Buffer The buffer in which the array is returned.
@retval EFI_SUCCESS The array of handles was returned.
@retval EFI_NOT_FOUND No handles match the search.
@retval EFI_BUFFER_TOO_SMALL The BufferSize is too small for the result.
@retval EFI_INVALID_PARAMETER SearchType is not a member of EFI_LOCATE_SEARCH_TYPE.
@retval EFI_INVALID_PARAMETER SearchType is ByRegisterNotify and SearchKey is NULL.
@retval EFI_INVALID_PARAMETER SearchType is ByProtocol and Protocol is NULL.
@retval EFI_INVALID_PARAMETER One or more matches are found and BufferSize is NULL.
@retval EFI_INVALID_PARAMETER BufferSize is large enough for the result and Buffer is NULL.
