[Android] Allow extension manager to load extension js from res/raw

This is step one of getting rid of assets for xwalk_core_library.
Because assets are not supported well for android library project.

Now XWalkExtensionManager will load extension js files from res/raw
first for internal extensions, then from assets if not found.

Fix "XWalkExtensionsIFrameTest.IFrameUsingDocumentWriteShouldNotCrash" test failure

The "XWalkExtensionsIFrameTest.IFrameUsingDocumentWriteShouldNotCrash"
test failed on Linux due to some pending events left after
"xwalk_test_utils::NavigateToURL()". The pending events were
prosessed after the corresponding web contents had been
already destroyed causing the crash.

Bump version to 5.34.95.0
[IVI][Runtime] Fix unable to install application on Tizen IVI 3.0 image.

The package install/uninstall/update for Tizen are designed to integrate
with AMD (Application Management Daemon) on Tizen mobile 2.x, not
compatible with Tizen IVI 3.0.

This is a temporary solution to revert to use macro OS_TIZEN_MOBILE, this
means install/uninstall/update won't work with AMD on Tizen IVI. We'll
add that support back later.
