Remove com.sun.java.browser.* from jdk repo

com.sun.java.browser.** belongs to plugin/deploy. These classes should not belong to the jdk repo. com.sun.java.browser.dom and com.sun.java.browser.net classes are legacy and only used by old plugin that was removed in JDK 8 (see JDK-8004321).

com.sun.java.browser.dom and com.sun.java.browser.net can be removed.
