[8u] RFR 8216401: Allow "file:" URLs in Class-Path of local JARs

[Verghese, Clive]

Hi Zhengyu, 

Instead of importing the writeToDisk function to the test, We could update the ClassFileInstaller to be similar to the one in tip. [1]

    Please review 8u backport of above CR.
    JDK13 patch does not apply cleanly. However, the fix itself applies 
    cleanly, just not the test.
    
    8u ClassFileInstaller does not have some APIs that exist in JDK13. 
    Therefore, I copied/pasted corresponding code from JDK13's 
    ClassFileInstaller into the test (writeClassToDisk and writeToDisk).
