Add VelocityTracker strategy to PlatformProperties

To make this property easier to use in both Java and native code, add it
to the PlatformProperties build target.
This will also allow specific devices to change their VelocityTracker
strategy.

Bug: 192439431
Test: verified manually by running 'adb shell setprop
persist.input.velocitytracker.strategy impulse && adb shell stop && adb
shell start' and enabling 'DEBUG_STRATEGY' in VelocityTracker.cpp, then
watching 'adb logcat | grep -i strategy' to see the strategy change from
'lsq2' to 'impulse'
