No longer report "native copy" when copying text in native selection …

…mode in browse mode (nvaccess#16262)

Related to nvaccess#16202 and nvaccess#16201.

Summary of the issue:
In NVDA's new native selection mode in browse mode for Firefox, and MS word / Outlook browse mode, when native copying to clipboard with control+c, NVDA would report "native copy". this message has proven confusing and or unpopular. Thus this pr removes the message.
therefore, now when copying text with control+c when native seleciton mode is turned on, in Firefox / MS word / Outlook browse mode, NVDA will not say anything at all, and just let the application react the way it normally would (E.g. MS word may announce "copy" via its UIA notification).

Description of user facing changes
NVDA will no longer announce "native copy" when copying text with native selection mode.

Description of development approach
the "native copy" message has been removed from the clipyToclipboard script in cursorManager.
MS word's own "copy" UIA notification message is no longer suppressed in browse mode.

+Copying text with ``control+c`` will pass straight through to Firefox, thus copying the rich content, rather than NVDA's plain text representation.
+Note however that as Firefox is handling the actual copy, NVDA will not report a "copy to clipboard" message in this mode. (#15830)
+- When copying text in Microsoft Word with NVDA's browse mode enabled, formatting is now also included.
+A side affect of this is that NVDA will no longer report a "copy to clipboard" message when pressing ``control+c`` in Microsoft Word / Outlook browse mode, as the application is now handling the copy, not NVDA. (#16129)
 - A new "on-demand" speech mode has been added.
 When speech is on-demand, NVDA does not speak automatically (e.g. when moving the cursor) but still speaks when calling commands whose goal is explicitly to report something (e.g. report window title). (#481, @CyrilleB79)
 - In the Speech category of NVDA's settings, it is now possible to exclude unwanted speech modes from the Cycle speech modes command (``NVDA+s``). (#15806, @lukaszgo1)
