Dynamically add the webview_zygote's preloaded APK to the zygote FD whitelist.
This refactors the whitelist to be a class, rather than just a static C array.
The whitelist can then be augmented dynamically when the package path is known
in the webview_zygote.
Test: m
Test: sailfish boots
Test: Enable Multi-process WebView in developer options, perform a search in GSA.
