ANDROID: GKI: Remove duplicates from symbol lists

Browse Source 
scripts/gen_gki_modules_headers.sh:

Add an option to only keep unique symbols during the
symbol list prep phase as for header generation symbol
list needs to be unique union of all vendor symbol
lists in an ascending order.

This reduces the array size and improves the lookup
time for the binary search.

Bug: 232430739
Test: TH
Fixes: 0a903fe828 ("ANDROID: GKI: Header generation fix and improvements")
