This CL cleans up tab grid metric names and regularizes how they are called.

All tab grid metrics are now named "TabGrid*". "Regular" is used instead of "NonIncognito" in metric names. Straightforward renames are as follows:

(All of the original names for these metrics were defined in the internal actions.xml file and will be obsoleted)
  MobileStackViewCloseTab -> MobileTabGridCloseControlTapped
  MobileTabSwitcherHeaderViewSelectDistantSessionPanel -> MobileTabGridSelectRemotePanel
  MobileTabSwitcherOpenNonIncognitoTab -> MobileTabGridOpenRegularTab
  MobileTabSwitcherOpenIncognitoTab -> MobileTabGridOpenIncognitoTab
  MobileTabSwitcherCloseNonIncognitoTab -> MobileTabGridCloseRegularTab
  MobileTabSwitcherCloseIncognitoTab -> MobileTabGridCloseIncognitoTab
  MobileTabReturnedToCurrentTab -> MobileTabGridDone

(The original names for these metrics were not defined anywhere!)
  MobileTabSwitcherPresented -> MobileTabGridEntered
  MobileTabSwitcherDismissed -> MobileTabGridExited

Some metrics that were tracked separately in the old stack view and table tab switcher are here consolidated into a single metric:

MobileTabSwitcherHeaderViewSelectIncognitoPanel, MobileStackViewIncognitoMode -> MobileTabGridSelectIncognitoPanel
MobileTabSwitcherHeaderViewSelectNonIncognitoPanel,  MobileStackViewNormalMode -> MobileTabGridSelectRegularPanel

The metrics for tab creation are now separated to distinguish use of the new tab button and the keyboard shortcuts. The relevant code is also restructured for this.

  MobileTabSwitcherCreateNonIncognitoTab -> MobileTabGridCreateRegularTab, MobileTabGridCreateRegularTabKeyboard
  MobileTabSwitcherCreateIncognitoTab -> MobileTabGridCreateIncognitoTab, MobileTabGridCreateRegularTabKeyboard
