Jack Franklin 7666031432 [DarkMode] fix darkmode generation to not include variables ...

Prior to this CL, if we gave the dark mode generation script a CSS
file that contained:

```
.foo {
  color: var(--override-some-custom-color);
}
```

The script would generate the following CSS:

```
.-theme-with-dark-background .foo,
:host-context(.-theme-with-dark-background) .foo {
  color: var(--override-some-custom-color);
}
```

But because the value of `color` is a variable, this CSS does nothing
that the original CSS won't do. Therefore the CL checks each rule for
any declarations that include `var(--` in them, and removes them from
the CSS that is sent to be dark patched.
