chart a11y: Drop bSendGlobally param from AccessibleBase::BroadcastAccEvent

Setting it didn't have any effect in practice:
If set to `true`, it resulted in
`vcl::unohelper::NotifyAccessibleStateEventGlobally` getting
called, which calls
`XExtendedToolkit::fireFocusGained` or
`XExtendedToolkit::fireFocusLost`, but the only implementations
in `VCLXToolkit` do nothing.

Interestingly, the documentation for `XExtendedToolkit` in
`offapi/com/sun/star/awt/XExtendedToolkit.idl` says:

>    @deprecated
>        This interface was only implemented in an intermediate developer
>        release anyway.
>
>    @since OOo 1.1.2

but the interface is still used in various places across the
code base...
