fix: (CXSPA-1128) - NgSelect double stop on mobile alternative fix

[Pio-Bar]

Ticket: CXSPA-1128

To avoid the console error the previous solution caused, we can hide the display value from the screen reader and instead provide it as a part of the aria-label. We can limit this solution to the mobile devices since the bug is only present for such.

I could not come up with a better solution that would satisfy the requirement. This feels a bit hacky to me, I would like @developpeurweb to share his opinion on this.
