oh-image - Allow embedding of SVG to oh-image and oh-image-card

[jsjames]

Dependent on #4345

This adds support to embed SVGs to any oh-image and oh-image-card (in addition to oh-canvas-layout and oh-plan-page).

In addition:

• converts the svg-embedded mixin to a composable which is reused across these components
• converts oh-canvas-layout and oh-plan-page to composition api and typescript
• adds appropriate svg-embedding fields in definitions (and adds some which were not listed, but are used in the ui)

Note:

• For oh-image and oh-image-card, the embeddedSvgActions can only be edited in the code editor and not directly in the UI. To support editing in ui will be more involved as it will require more extensive changes throughout the widget editor and other components.
• Also, during the typescript conversion of oh-canvas-layout, mutli-select drag/drop does not work on oh-canvas-layout #4324 was discovered where multi-select / moves is not working. This was not fixed in this PR and will be addressed separately.
