Cycles: code refactor to bake using regular render session and tiles

There should be no user visible change from this, except that tile size
now affects performance. The goal here is to simplify bake denoising in
D3099, letting it reuse more denoising tiles and pass code.

A lot of code is now shared with regular rendering, with the two main
differences being that we read some render result passes from the bake API
when starting to render a tile, and call the bake kernel instead of the
path trace kernel.

With this kind of design where Cycles asks for tiles from the bake API,
it should eventually be easier to reduce memory usage, show tiles as
they are baked, or bake multiple passes at once, though there's still
quite some work needed for that.

Fix T76734: Changing Envelope FModifier controlpoints missing update

Issue is that update functions defined in
`rna_def_fmodifier_envelope_ctrl` (namely `rna_FModifier_update`) are
actually never called.

This is because UI code for FCurve modifiers often does not use RNA
buttons but uses custom update functions (or non at all). For example,
rB9a88bd55903a did this for the generators, envelope control points did
not have this at all.

This is now changed to use RNA buttons for the envelope control points,
this could done for other non-RNA buttons as well to get rid of
'validate_fmodifier_cb()'.

Fix T76277: Remove wrong cast in rna_NodeTree_update

This patch fixes T76277 by removing the incorrect cast from
`ptr->data` to `bNode`. The address of `ptr->owner_id` and
`ptr->data` both point to the node tree. Passing the node tree
incorrectly as a node into the `ED_node_tag_update_nodetree`
corrupts the data, because it attempts to set flags on the
node.
