init: Supplement description to property action usage 



Early set properties in DT or over the command-lines do not trigger
property-change events until boot stage.

Bug: 383738769
Test: After changing the action command line to tie to `early-boot`
event, the action is triggered earlier

Note that, for bootloader-provided properties (ro.boot.*), their action cannot be

auto-triggered until `boot` stage. If they need to be triggered earlier, like at `early-boot`

stage, they should be tied to the `event`. For example:



`on early-boot && property:a=b`.
