Closes godotengine/godot-docs#3667.
Supersedes #39405.

PackedScene: Prevent crash when root node has `parent` attribute

GDScript LSP: Fix crash in notify_client

Removed variables in EditorSceneImporterAssimp::import_scene that became unused.

Respect 'mesh compression' editor import option in Assimp and glTF importers [master]

VariantParser: Fix crash on malformed vectors

The crash happens further down when setting an invalid owner in
`Node::_set_owner_nocheck` but I couldn't figure out how to fix it.

But here the proper fix is to catch the invalid scene file early on
and fail loading it.

Part of #17372.

Each time `r_err_str` is set, we should return a parse error.

Removed redundant `return OK;` which were already handled after the big
`if`/`else if`/`else` for `TK_IDENTIFIER`.

Part of #17372.

`latest_client_id` now defaults to `-1` (invalid ID) instead of `0`.

Also fix typo in notification `gdscrip_client/changeWorkspace`,
and fix argument names in method binds.

Fixes #39375.

Restore capture caches when missing

Removed variables and #include in EditorSceneImporterAssimp::import_scene that became unused after the recent commit ec1bf96e(#39363).
