Rename initial_pos to initial_rect in ShowWidget and ShowView IPCs.

Rename initial_pos to initial_rect in ShowWidget and ShowView IPCs.

These IPCs hold this param as a gfx::Rect and the RenderWidget and RenderView
set the size. On the receiving end, the size is sometimes used so initial_pos
was a misnomer.

This is a mechanical rename, there should be no functional difference.

Avi, does this look ok? I renamed the IPC params to match the name change made
in https://codereview.chromium.org/894193003 since they're really carrying the
window rect. I made the change all the way down the call chain from the IPC
handlers.

Also, if it looks good, can I just TBR the rest since it's a mechanical change?

Please specify actual TBR reviewers next time. I don't think it's OK for code
changes to land like this.
