ign -> gz : Support Citadel to Fortress Forward Port

[methylDragon]

Main Parts

Header Migration

Two Three parter here!

1. Remove redundant namespace references (if there's a prior using namespace XXX instance, this group of PR gets rid of MOST of the redundant namespace references.)

• Most usefully, this removes a lot of ignition:: namespace references

2. Migrate headers ignition -> gz. Create ignition -> gz redirection headers and use them locally (also use new namespaces)
3. MIgrate include statements, folded into (2) Upon merge of (2), migrate all include statements to gz

We need (2) to merge first because otherwise as we're merging (3) downstream packages will break.

(2) must be merged in topological order.

Additionally, to not break ABI, ignition has to be the primary/canonical namespace. So usage of gz will redirect to ignition.
Also, some config.hh include statements have been added, and msgs was skipped because its headers are generated based off the directory of those headers.

Building Locally

To test locally, you need to manually install the deps (we can't use the script on the installation guide because certain dependencies can't be found on jammy and it'll fail, so I had to edit the actual list (and this is what you see) :> )

Part I: Remove redundant namespace references

Created with a very hacky script (but good enough!) I did some hacky stuff to deal with the edge-cases, but it means some instances might have slipped through.

Because of the hacky stuff being done, the script can't be dropped in easily, but the structure can be followed if needed for other cleanup tasks. So I won't put it into release-tools.

Additional Note

Additionally, I couldn't get gz-sim to compile without adding an include statement for optional:

Part II: Create gz -> ignition redirection headers

Created with more hacky scripts.
I pulled from the install space, then redirected it.
