shiboken6: Determine function types in the code model

Extend the _FunctionModelItem function type enumeration
by operator types and determine them by name or from clang.
Split the bitwise operators into shift and other bitwise operators
for stresm operator detection.

Similarly, add operator type values to
AbstractMetaFunction::FunctionType and replace the isOperator()
checks accordingly. Remove the unused isOtherOperator() function.
Rename AbstractMetaFunction::isNormal() to needsReturnType()
for clarity.

Rewrite the binary operator search in AbstractMetaBuilder by
checks based on enumeration value and rewrite traverseOperatorFunction
to return a bool so that shift operators are found when stream
operator is not applicable.

Rewrite the function query functions of AbstractMetaClass to also
use the enumeration values.

Pick-to: 6.0
