Member avatars without canvas (#9990)

* Strict typechecking fixes for Base/Member/Avatar

Update the core avatar files to pass `--strict --noImplicitAny` typechecks.

* Add tests for Base/Member/Avatar

More thoroughly test the core avatar files. Not necessarily the most thorough,
but an improvement.

* Extract TextAvatar from BaseAvatar

Extracted the fallback/textual avatar into its own component.

* Use standard HTML for non-image avatars

Firefox users with `resistFingerprinting` enabled were seeing random noise
for rooms and users without avatars. There's no real reason to use data
URLs to present flat colors.

This converts non-image avatars to inline blocks with background colors.

* Have pills use solid backgrounds rather than colored images

Similar to room and member avatars, pills now use colored pseudo-elements
rather than background images.
