Migrate StarboardBridge JNI functions in android_main.cc (#4632)

Remove @UsedByNative annotations for beforeStartOrResume and
beforeSuspend, for they are no longer needed in ApplicationAndroid.
Reference b/377042903.

Remove getLocalInterfaceAddressAndNetmask and isCurrentNetworkWireless,
for it's not used in Chrobalt.

Remove @UsedByNative annotations for getDisplaySize, for it's never used
in native code.

Change UA related fields getIsAmatiDevice, getBuildFingerprint,
getPlayServicesVersion to @CalledByNative, we are currently not using
them in UserAgentPlatformInfo::ToString(), but might need them for
cobalt/browser/client_hint_headers.cc in the future.

Migrate the rest of JNI calls in
starboard/android/shared/android_main.cc to Chromium standard JNI,
When testing locally:
startDeepLink is set with empty string.
GetArgs retrieves url.
