[SB][Screen Chips] Use correct icon for share-to-app chip.

Why didn't I use this icon initially you may ask? What a lovely
question. I thought this icon didn't exist when I first started the
screen chips project, but Git tells me the icon was added in 2022, so
I have no idea how I didn't find it. An unsolvable mystery!

Bug: 332662551
Flag: com.android.systemui.status_bar_screen_sharing_chips
Test: Share screen to another app -> verify chip has the "present to
all" icon
