sdm660-common: Ship copy of API 28 cgroups/task_profiles.json in vendor

Browse source 
Google's prebuilt cgroups.json and task_profiles.json for products
launched with previous API levels only covers
ro.product.first_api_level >= 28. [1]

Xiaomi sdm660 devices were launched with Nougat/Nougat MR1/Oreo (API levels 24-26), so schedtune and
task groups are completely broken. Since the system also checks
/vendor/etc for vendor profiles, make a copy of cgroups_28.json
and task_profiles_28.json and ship them to /vendor/etc. Profiles
for previous API levels are all the same anyway.

Test: boot and check /dev/stune/

[1] system/core/libprocessgroup/profiles/
