Misra false positive fixes for rules 8.7 and 5.9 (#3844)
* Fix misra 8.7 false positives on single function usage

When there is a single usage of a function, we should first check if the
file it is used in, is the same one it was defined in. When this is not the
case, there is no violatior to be reported.

* Fix misra rule 5.9 false positives for exception

The exception for rule 5.9 described in the guidelines allows for
multiple definitions of internal linkage obejcts when these regard a
static inlined function defined in the same header file.

* Fix neglecting of inline keyword flag upon simplifications

When the inline keyword is being "simplified" and the inline flag is
degated to the next token. However, this information might be lost if the next
token itself is simplified/deleted in a futher pass. Therefore, we must
propagated the flag to all the next named tokens, so we can make sure the
function name token itself is tagged with this property.

* add tests for misra addon rules 8.7 and 5.9

Fix check for misra addon in executeAddons. (#3819)
In the CppCheck::executeAddons function, a check that specifically tests
for the misra add-on, was not taking into account the cases when the
addon is identified with the '.py' extension or indirectly via json.
This resulted in the add-on not being executed a second time which is
needed to detected some of the misra violations. By using the AddonInfo
class name field, the addon name is uniformized for all these cases and
the add-on executed a second time.

Fix #10671: functionConst FN with begin/end and const_iterator (#3749)
Check if the iterator is assigned to a const_iterator or
const_revese_iterator, in which case it is possible the function can be
const. Unfortunately, it is not possible to remove the hard coding of
cbegin, cend, crbegin and crend due to the need to handle auto, as in
the following code snippet:

    void cbegin_auto(void)
    {
        for (auto it = m_str.cbegin(); it != m_str.cend(); ++it) {;}
    }
