Add encoding override support for Chrome frame. With this change, users can override current page encoding in Chrome Frame via clicking IE's encoding menu.

Unfortunately this change does not work on IE8 since the encoding menu is off on IE8.

This change was from http://codereview.chromium.org/460036/show, which was on a temporary machine which I can not access from China now. I will re-create the patch, make some modifications according to previous reviewers' comments. now I send to you for review.

BUG=24040
TEST=none

+// The following macro is to define the mapping of IE encoding menu item to
+// corresponding available encoding name in Chrome. For each encoding
+// definition, there are three fields.
+// The first one is the definition name of encoding menu item in IE.
+// The second one is execution id of the encoding menu item in IE, starting
+// from 3609(IDM_MIMECSET__FIRST__) to 3699(IDM_MIMECSET__LAST__) end. For
+// the details, please refer to mshtmcid.h.
+// The last one is the available encoding name of the IE encoding menu item
+// in Chrome. If the encoding menu item does not have corresponding encoding
+// in Chrome, it will be "unknown".
+// So far we don't support the encoding auto detect since we can not control
+// the status of encoding menu, such as toggle status of encoding auto detect
+// item on the encoding menu.
