Support SVG Text Rendering in egui_extras (#5979)

**Added**
* Create `svg_text` feature flag to support text rendering & loading of
system fonts.

**Changed**
* Updates `resvg` to `0.45`.
* Adds `usvg::Options` field to the `SvgLoader` structure.
* Change function signatures to support passing `usvg::Options` to
downstream `load_svg_bytes_with_size`.

**Additional Info**
* I used this PR as a reference:
#4659. @xNWP can you see if this
adequately resolves your concern from your original PR?
* Closes #5977 (we may want to open
another issue for my other thoughts in this issue)
* Also, I would like to thank @xNWP and their original PR for being a
good reference for this one.
* [x] I have followed the instructions in the PR template
