Split out a minimal target from content_java to use in the base module

This reduces the base dex size in trichrome by 0.5MB, which should help
both memory usage and startup time in child processes with isolated
splits enabled. Unfortunately we can't do the same for monochrome at the
moment because WebView still needs the full content_java target.

Bug: 11674041

Binary-Size: The method count is inflated because methods are moving
Binary-Size: from the base module -> chrome module, and it doesn't look
Binary-Size: like these are counted right. The increase in
Binary-Size: Combined_unique methods is only +13.
