Ref: #132179 Renames: - `Editing.act_seq` -> `Editing.act_strip` - `SequenceModifierData` -> `StripModifierData` - Its member `mask_sequence` is now `mask_strip`. - `MetaStack.parseq` -> `MetaStack.parent_strip` - Remaining function names/parameters that were not dealt with in #132748 - Various references to `seq` or `sequence` throughout code and docs when referring to a strip Also moves `_get` to the end of the renamed function names where applicable for standardization (unless "by" or "from" are used). There should be no changes to current behavior. Pull Request: https://projects.blender.org/blender/blender/pulls/138077
