[WinCairo] Use RenderThemeAdwaita instead of RenderThemeWin

RenderThemeWin doesn't work with UseGPUProcessForDOMRenderingEnabled.
Let's use RenderThemeAdwaita. Piggy backed on GTK efforts.

The code below doesn’t look platform-specific. Can we instead just use "#else" here? Or is this actively specific to PLATFORM(WIN)?

Typically it’s best to check isNull() instead of using ! for WTF::String. But also, maybe FileSystem::readEntireFile already harmlessly fails if passed a null string, so maybe we don’t need this check.

I'm not a fan of the variable shadowing here.

The webkitBundlePath code is specific to PLATFORM(WIN) at this time.
