Depsgraph: Add some data builder logic to corresponding function

Depsgraph: cleanup, no functional changes

Depsgraph: Disable timing profile

Despgraph: Optimize cycles detection algorithm

The idea is simple: when falling back to one of the nodes which was partially
handled we "resume" checking outgoing relations from the index which we stopped.

This gives about 15-20% depsgraph construction time save.

Depsgraph: Speedup initial rig build time

We don't need to sort bone channels, it's all taken care about
by the depsgraph itself.

Gives up to 30% initial rig construction time speedup.

fix building depsgraph after recent changes

Depsgraph: Move class implementation from header to implementation files

This is more proper way to go:

- Avoids re-compilation of all dependent files when implementation changes
without changed API,

- Linker should have much simpler time now de-duplicating and getting rid
of redundant implementations.

Depsgraph: Move key implementation from header to dedicated file

Depsgraph: Do not rely on indirectly included cstring

Also add comment why exactly cstring is needed.

Depsgraph: Fully switch from string to const char*

This brings up to 10-20% depsgraph build time improvement in the layout
files from the studio repository.

Depsgraph: Cleanup, operation has name, not description

Hopefully should make things more clear here.

Depsgraph: Remove unused function

A residue from times where we thought to do partial graph updates,
which we are not committing any time soon.

Depsgraph: Add extra name tag for operation nodes

The idea here is to address issue that name on it's own is not
always unique: for example, when adding driver operations the
name used for nodes is the RNA path (and multiple drivers can
write to different array indices of the path). Basically, now
it's possible to pass extra integer value to distinguish
operations in such cases.

So now we've already switched from sprintf() to construct unique
operation name to pass RNA path and array index.

There should be no functional changes yet, but this work is
required for further work about replacing string with const
char*.

Depsgraph: Use const char for component API

Depsgraph: Use const char instead of string in part of drivers construction

Fix T49826: NEW-DEPSGRAPH - Texture is not updated after changing its space color

The issue was caused by image ID nodes not being in the depsgraph.

Now, tricky part: we only add nodes but do not add relations yet. Reasoning:

- It's currently important to only call editor's ID update callback to solve
the issue, without need to flush changes somewhere deeper.

- Adding relations might cause some unwanted updates, so will leave that for
a later investigation.

Depsgraph: Remove some includes which seems unused

Depsgraph: Add code for timing despgraph builder

Depsgraph: Switch away form string to const char* for node names

There is no real reason to have nodes storing heap-allocated name
and description. Doing this increases amount of allocations during
dependency graph building, which usually means somewhat slowness.

We're temporarily loosing some eyecandy in the graphviz visualizer,
but those we can bring back as a part of graphiz dump (which happens
much less often than depsgraph build).

This will happen in multiple commits for the ease of bisect in the
future just in case this causes any regression. This commit contains
ID creation API changes.

Depsgraph: Remove prototype of unused and non-implemented method
