Make BrowserAccessibilityManager cross platform. Step 1.

1. Move windows browser accessibility source and headers into chrome\browser\accessibility
2. Rename BrowserAccessibilityManager to BrowserAccessibilityManagerWin and BrowserAccessibility to BrowserAccessibilityWin
3. Add base classes that will eventually contain common browser accessibility code.
