release notes for cppcheck-2.11

- The platform type 'Unspecified' within .cppcheck projects has been deprecated and will be removed in Cppcheck 2.14. Please use 'unspecified' instead.
- It is no longer necessary to run "--check-config" to get detailed "missingInclude" and "missingIncludeSystem" messages. They will always be issued in the regular analysis if "missingInclude" is enabled.
- "missingInclude" and "missingIncludeSystem" are reported with "-j" is > 1 and processes are used in the backend (default in non-Windows binaries)
- "missingInclude" and "missingIncludeSystem" will now cause the "--error-exitcode" to be applied
- "--enable=information" will no longer implicitly enable "missingInclude" starting with 2.16. Please enable it explicitly if you require it.
- The `constParameter` and `constVariable` checks have been split into 3 different IDs based on if the variable is a pointer, a reference, or local. The different IDs will allow users to suppress different const warning based on variable type.
    - `constParameter`
    - `constParameterReference`
    - `constParameterPointer`
    - `constVariable`
    - `constVariableReference`
    - `constVariablePointer`
