Subject: [PATCH] [clang 11] fix build errors due to -WWc++11-narrowing

https://bugs.webkit.org/show_bug.cgi?id=211193

Reviewed by Adrian Perez de Castro.

Fixes the following errors,

* html/HTMLMediaElement.h:
(WebCore::HTMLMediaElement::hasRenderer const):
MediaElementSession was implicitly casting a pointer to a bool,
which is not allowed with modern Clang checks. Add a helper method
to encapsulate the now required static_cast<bool>.
* html/MediaElementSession.cpp: Use the new helper method to see
if the HTMLMediaElement has an associated renderer.
(WebCore::MediaElementSession::updateMediaUsageIfChanged):
* style/StyleResolver.cpp: This was calling MediaQueryEvaluator {
"all" }; and seemingly expecting to cast a const char[] to a bool,
or maybe String? It's confusing because of the MediaQueryEvaluator
API. If it was implicitly converting to bool then that could be
unintentional. Such casts are not allowed either now. The
MediaQueryEvaluator's default constructor says it returns true for
"all", which appears to be the original intent of this call, so I
replaced it with that.
(WebCore::Style::Resolver::Resolver):
