RedfishPkg/JsonLib: Ignore the build error of conditional expression. 

Ignore the build error of assignment within conditional expression.
Add build option to ignore the build error of "assignment within
conditional expression".
This build error is caused by the macros defined in open source
project jansson header file jansson.h.

- json_object_foreach
- json_object_foreach_safe
- json_array_foreach

We use build option to avoid the build errors on Visual Studio
(GCC doesn't havvve this problem) for now. Already sent an email
to jansson open source community to revise these macro as Leif's
suggestion as below,

for (key = json_object_iter_key(json_object_iter(object));    \
       key;                                                   \
       key = json_object_iter_key(                            \
            json_object_iter_next(object,
json_object_key_to_iter(key)))) { \
       value =
json_object_iter_value(json_object_key_to_iter(key));         \
      if (!value) \
        break; \
  } \

We will remove this build option once the patch is accepted and
upstreamed.
