fix(android): added ServerPath object and building options for setting initial load from portals

[carlpoole]

Adds a ServerPath object and mechanics for Portals and live updates to load directly instead of after the webview has already loaded. Fixes issue with observable flash or Page Not Found error before content loading.

Will port this to 4.x when upgrading Portals for Cap 4 support.

Example use

var bridgeBuilder = Bridge.Builder(this)
.setInstanceState(savedInstanceState)
.setPlugins(initialPlugins)
.setConfig(config)
.addWebViewListeners(webViewListeners);

if (portal?.liveUpdateConfig != null) {
liveUpdateFiles = LiveUpdateManager.getLatestAppDirectory(requireContext(), portal?.liveUpdateConfig?.appId!!)
bridgeBuilder = if (liveUpdateFiles != null) {
    bridgeBuilder.setServerPath(ServerPath(ServerPath.PathType.BASE_PATH, liveUpdateFiles!!.path))
} else {
    bridgeBuilder.setServerPath(ServerPath(ServerPath.PathType.ASSET_PATH, startDir))
}
} else {
  bridgeBuilder = bridgeBuilder.setServerPath(ServerPath(ServerPath.PathType.ASSET_PATH, startDir))
}

bridge = bridgeBuilder.create()```

Looks great!

@carlpoole Is there a reason to not add this to main as well? That would give us a jump on Cap 4 support for Portals without having to wait for a native cap release to potentially get worked on next sprint.

No I was just going to wait for this PR to be approved/merged and then open a copy on 4.x

Oh okay, I misunderstood what you meant in the comment. Sounds good! 👍
