Subject: [PATCH] GCC: DOMRect constexpr equal operator depends on non constexpr operators

Make accessors of DOMRectReadOnly constexpr so the equal operator can be
also constexpr.

../../third_party/blink/renderer/core/geometry/dom_rect.h: In function ‘constexpr bool blink::operator==(const blink::DOMRect&, const blink::DOMRect&)’:
../../third_party/blink/renderer/core/geometry/dom_rect.h:38:15: error: call to non-‘constexpr’ function ‘double blink::DOMRectReadOnly::x() const’

Bug: 819294
