Bug 205196 – Prefix CSS selectors with all applicable CSS groupings when generating a ChangeLog

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Devin Rousso]

When modifying a style inside a @media grouping, `prepare-ChangeLog` currently adds the media query as a separate line instead of prefixing the modified rule's selector.

e.g., modifying
```
    @media (prefers-color-scheme: dark) {
        body {
            ...
        }
        div {
            ...
        }
    }
```
would generate
```
    (@media (prefers-color-scheme: dark)):
    (body):
    (div):
```
instead of
```
    (@media (prefers-color-scheme: dark) body):
    (@media (prefers-color-scheme: dark) div):
```

This also needs tests. See  Tools/Scripts/webkitperl/prepare-ChangeLog_unittest

Normally perl requires a semicolon. This happens to be the last statement of a block so it isn't required but it would be good to have.
