[Feature]: Accept icon font glyphs and SVG for notification button images

Proposal: Accept icon font glyphs and SVG for notification button images

Summary

Currently, according to documentation, a ToastButton only accepts rasterized images for displaying icons.

I'd like to suggest to provide options to allow an icon font glyph or SVG image alternatively.

Rationale

• Rasterized images don't scale well on deviating Windows scaling settings
• Converting glyphs from Segoe MDL2 Assets is cumbersome and tedious
• Theming can easily be applied to both, font glyphs and monochrome SVG files.
