Subject: 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.
