LibWeb: Add coverage test for calc() usage

Browse Source 
Ignoring the fact that we should serialize a simplified form of calc()
expressions, the following are wrong:

- grid-auto-columns
- grid-auto-rows
- grid-template-columns
- grid-template-rows
- transform-origin

Generated in part with this python script (though I've since iterated on
the output repeatedly so it's quite different):

```py
import json
properties_file = open("./Userland/Libraries/LibWeb/CSS/Properties.json")
properties = json.load(properties_file)
for (key, value) in properties.items():
    if not 'valid-types' in value:
        continue
    if 'longhands' in value:
        continue
    valid_types = value['valid-types']
    for type_string in valid_types:
        name, *suffix = type_string.split(None, 1)
        match name:
            case 'integer' | 'number':
                print(f'{key}: calc(2 * var(--n));')
            case 'angle':
                print(f'{key}: calc(2deg * var(--n));')
            case 'flex':
                print(f'{key}: calc(2fr * var(--n));')
            case 'frequency':
                print(f'{key}: calc(2hz * var(--n));')
            case 'length':
                print(f'{key}: calc(2px * var(--n));')
            case 'percentage':
                print(f'{key}: calc(2% * var(--n));')
            case 'resolution':
                print(f'{key}: calc(2x * var(--n));')
            case 'time':
                print(f'{key}: calc(2s * var(--n));')
```
