Move ENABLE_RESOLUTION_MEDIA_QUERY to a runtime flag, start running tests again

[Sam Sneddon [:gsnedders]]

We haven't compiled with this enabled since Blink forked, so it's likely that it doesn't quite compile and that the tests don't all pass.

Given there's no reason for this to be a compile-time switch, let's make this a run-time switch (which also means we don't regress compiling!) and make sure the tests aren't skipped.

This should be writable as `String message = mediaQueryMessage`; No need for the explicit String constructor call.

That said, this whole thing using replace seems very unnecessary. I would just use makeString() for both of them. Something along the lines of:

        ASSERT(value.isDotsPerInch() || value.isDotsPerCentimeter());
        auto replacementUnit = value.isDotsPerInch() ? "dpi" : "dpcm";
        auto lengthUnit = value.isDotsPerInch() ? "inch" : "centimeter";

        auto message = makeString("Consider using 'dppx' units instead of '", replacementUnit, "', as in CSS '", replacementUnit, "' means dots-per-CSS-", lengthUnit, ", not dots-per-physical-", lengthUnit, ", so does not correspond to the actual '", replacementUnit, "' of a screen. In media query expression: ", serializedExpression);

Why are these failing now?

Yeah, I don't disagree; was just trying to keep changes beyond re-enabling the feature minimal. But I guess I can do that.

I was trying to land this with minimal changes beyond re-enabling the flag. Digging into this now, though got a bit held up by our sheer lack of documentation of any of internals.* or testRunner.* and struggling to find appropriate APIs. My suspicion it only ever passed on the Chromium port.
