Logic to handle shepkeys datablocks in helper in 'make local' code that
checks which ID should be copied, and which can be directly made local,
was wrong.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).
No functional changes.
Mpving utils from idcode to idtype proved to be somewhat painful for
some reasons, but now all looks good.
Had to add a fake/empty shell for the special snowflake too,
`ID_LINK_PLACEHOLDER/INDEX_ID_NULL`...
Embedded data should always be considered as outside of Main database
here.
Note that it's a bit of an edge case to decide whether those should
always have their `LIB_TAG_NOMAIN` set too, or not? For now, let's keep
things as they are here.
'Private' can be a rather confusing term, especially when considering
its meaning in programming languages.
So now root node trees and master collections are 'embedded' IDs
instead.
Only covers direct usages of new callbacks from IDTypeInfo.
We still have a lot of those switch/case, many can probably go away
with minimal refactor now, but that will be for later.
This was particularly strange because we had a _free_data() function.
But still the one I replaced was of course the _free() one.
And we should rename the _free_data_ function later to avoid confusions.
"session-wise" here mean while editing a same .blend file. So creating
or opening a new one will reset the uuid counter. This should avoid any
overflow in practice.
Only IDs added to Main database get an uuid, runtime-only ones are not
affected.
This is intended to provide undo with a way to find IDs across several
'memory realms' (undo speedup project).
No behavior change is expected from this commit itself.

Introduce new IDTypeInfo structure.
Each ID type will have its own, with some minimal basic common info,
and ID management callbacks.
This patch only does it for Object type, for demo/testing purpose.
Moving all existing IDs is a goal of next "cleanup Friday".
Note that BKE_idcode features should then be merged back into BKE_idtype -
but this will have to be done later, once all ID types have been properly
converted to the new system.
Another later TODO might be to try and add callbacks for file read/write,
and lib_query ID usages looper.
This is part of T73719.
Thanks to @brecht for initial idea, and reviewing the patch.

Instead of using anonymous booleans flags, also allows to keep the same
behavior in all cases, without needing special handling from calling
code for our beloved oddballs object proxies...
Handling those through different ways /might/ be needed sometimes, but
in most case this is just a nest of issues, since you can easily forget
to take them into account.
Note that this should be a 'non-functional' change, as this new behavior
is not used anywhere yet.
Using a struct here allows to change given parameters to the callbacks
without having to edit all callbacks functions, which is always noisy
and time consuming.
