mapper: Add GetAssociatedSubTreePathsById and GetAssociatedSubTreeById

dbus-interface change in:
https://gerrit.openbmc.org/c/openbmc/phosphor-dbus-interfaces/+/69999

This commit implements two new methods: GetAssociatedSubTreePathsById
and GetAssociatedSubTreeById. These methods retrieve the paths of
associated endpoints corresponding to the provided identifier, filtering
based on their association with specified endpoint interfaces.

GetAssociatedSubTreePathsById returns the D-Bus paths of associated
endpoints, while GetAssociatedSubTreeById retrieves a dictionary of
D-Bus paths of associated endpoints mapped to corresponding services
associated with the provided identifier.

Tested:
'''
busctl call -j "xyz.openbmc_project.ObjectMapper" "/xyz/openbmc_project/object_mapper" \
"xyz.openbmc_project.ObjectMapper" "GetAssociatedSubTreePathsById" ssassas \
"chassis" \
"/xyz/openbmc_project/inventory" \
1 "xyz.openbmc_project.Inventory.Item.Chassis" \

clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.

mapper: Add Associated subtree method definition

dbus-interface change in:
https://gerrit.openbmc.org/c/openbmc/phosphor-dbus-interfaces/+/57821

Create new mapper function to make subtree call and association call at
the same time. With the association definition, we will have more
endpoints to fetch and verify that it is actually the resource that we
are looking for. We need to verify that it has the expected interface to
confirm that it is right device. In the current workflow this will take
two dbus calls to the mapper to get the association and the subtree.

This change aims to reduce that down to one by combining the two
operations. It will not significant performance increase for the daemons,
but it can help reduce the load on the dbus-broker.service.

Tested:
```
