In the file tree, the icons are not vertically centered, which affects
the overall visual consistency.
Currently, the icons of submodules and symlinks do not adopt the value
of entryIcon, resulting in inconsistent icon display.

Percentage-based `border-radius` [creates undesirable
ellipse](https://jsfiddle.net/silverwind/j9ko5wnt/4/) on non-square
content. Instead, use pixel value and use same wording `full` like
tailwind does, but increast to 99999px over their 9999px.
Previously, the citation js would load every time when opening a citable
repo. Now it only loads when the user clicks the button for it. The
loading state is representend with a spinner on the button:

1. Fine tune the CSS styles, and add more examples
2. Add necessary "dimmer" animation for modal dialogs, otherwise the UI
seems flicking (follow #26469)
## Changes
- no more hardcoded `border-radius`es (apart from `0`)
- no more value inconsistencies
- no more guessing what pixel value you should use
- two new variables:
- `--border-radius-medium` (for elements where the normal border radius
does not suffice)
- `--border-radius-circle` (for displaying circles)

The "btn-octicon is-loading" was introduced by #21842 , it is only used
by the "Copy Content" button, but the "btn-octicon" selector would
affect too many uncertain elements.
Now there is a general "small-loading-icon" class, so the "btn-octicon
is-loading" could be removed.
Removes all dropdown and dimmer animations. Works everywhere as far as I
can tell, but need to give this thorough testing. Removes around 70kb
JS/CSS.
Note, I'm not 100% sure regarding the various callbacks, those will need
more investigation, but it appears to work nonetheless.

Reorganize various CSS files for clarity, group together by subdirectory
in `index.css`. This reorders some of the rules, but I don't think it
should introduce any issues because of that.
