ui: Loader amends/improvements (#10181)

* ui: Loader amends/improvements

1. Create a JS compatible template only 'glimmer' component so we can
use it with or without glimmer.
2. Add a set of `rose` colors.
3. Animate the brand loader to keep it centered when the side
navigation appears.
4. Tweak the color of Consul::Loader to use a 'rose' color.
5. Move everything loader related to the `app/components/` folder and
add docs.

# BrandLoader
Initial loader full brand logo as opposed to the brand submark logo.
The component is a little strange in how you configure it (a CSS-like `@width`
and `@color` properties and the subtitle as a further component), but this is due to use
wanting to source this in a JS only environment (without Glimmer/Handlebars)
during compilation of the static `index.html` file. For this reason the
template sourcecode should use extremely minimal handlebars syntax.
Also, we want the logo to appear as soon as possible, so before any CSS has
loaded, so we define its color in attributes instead of CSS.
```hbs preview-template
<div style="position: relative;height: 300px;">
<BrandLoader
@width="198"
@color="#e07eac"
>
</BrandLoader>
</div>
```
```hbs preview-template
<div style="position: relative;height: 300px;">
<BrandLoader
@width="394"
@color="#8E96A3"
>
<BrandLoader::Enterprise />
</BrandLoader>
</div>
```
## Arguments
| Argument | Type | Default | Description |
| --- | --- | --- | --- |
| `width` | `Number` | | The width for the base SVG for the logo |
| `color` | `String` | | A hexcode color value for the logo |
| `subtitle` | `String` | | When used with JS you can pass extra DOM in here that will be yielded in the same position as the `{{yield}}`|
