I18n: make several parts of the UI translatable

- batch rename
- keyframe settings
- tool name in Tool properties header
- tool name in Tool properties Drag (fake) enum

- new file templates
- new preset
- new text datablock
- new collection datablock
- new geometry nodes (modifier and node group)
- new grease pencil data (layers and materials)
