One addition: we should probably also increment the appropriate histogram buckets in ContextMenu.SelectedOption.Link --

1) "Open in new tab"
2) "Open in incognito tab"

Turns out MobileContextMenuOpenLinkInNewTab was deprecated in https://chromium.googlesource.com/chromium/src/+/a4cb4af3543c3fdd6a6bcc4803c2d1a44ce79acb%5E%21/tools/metrics/actions/actions.xml

Lei is adding new buckets for each new case to ContextMenu.SelectedOption.Link.

[Android] Record user actions of new context menus for CCT

Add the logic to record user actions for the newly added context
menus ("Open in new Chrome tab", "Open in Chrome incognito tab",
"Open in browser") for CCT. Also record the user action of "Open in
Chrome" for Fullscreen mode.

Change the title from "Open in Chrome incognito tab" to "Open in
incognito tab" since the translation for the former one needs too much
characters to show on the small screen devices.

Alex, for context on the .grd change -- we found out during initial translation that the string we were planning to use was too long in a few languages. We circled back to UI review and decided to drop "Chrome."

(This merge also updates a histogram that UI reviewers asked us to monitor.)

Approved for M58 branch 3029, we still have time to take the string change.
