Support skipping onboarding with build flag or for internal builds

Task/Issue URL: https://app.asana.com/0/608920331025315/1209378492776844

Description

Adds a quick way to shortcut to the end of onboarding, offering a one-tap way to become fully onboarded from the pre-onboarding flow. It does this by surfacing a button to Skip Onboarding.

The skip button will only show up for builds which:

• are internal build type,
• OR were built with the gradle flag -Pskip-onboarding

The button will show up after the remote config has been successfully downloaded.

Steps to test this PR

ℹ️ Add logcat filter: message~:"App configuration sync was successful”

Play build type, no skip flag

• Fresh install, with play type (no skip build flag). e.g., ./gradlew installPD
• Launch the app and wait for privacy config to download
• Verify the skip button does not appear

Play build type, with skip flag

• Fresh install, with play type and include skip build flag. e.g., /.gradlew installPD -Pskip-onboarding
• Launch the app and wait for the privacy config to download
• Verify the skip button does show
• Tap the skip button; verify you are taken to the new tab screen with no more onboarding
• Kill and relaunch the app; verify you don’t see onboarding

Internal build type, no skip flag

• Fresh install, with internal type (no skip build flag). e.g., /.gradlew installID
• Launch the app and wait for the privacy config to download
• Verify the skip button does show
• For completeness, this time do not skip onboarding. Complete onboarding as normal and verify everything works as usual.

Internal build type, with skip flag

• Fresh install, with internal type and include skip build flag. e.g., /.gradlew installID -Pskip-onboarding
• Launch the app and wait for the privacy config to download
• Verify the skip button does show
