RFR 8242260: Remove customizable ContentSigner from jarsigner

[Sean Mullan]

We never actually deprecated the com.sun.jarsigner package with a 
forRemoval=true flag, so while it may be very low-risk to remove these 
APIs, I feel that we should not remove it w/o prior notice.

I would suggest adding the forRemoval=true for this package/APIs 
instead, and plan on removing it in JDK 16 or 17.

I'm ok with removing the jarsigner options because the man page already 
warned that they may be removed.
