8358099: PEM spec updates

[ascarpino]

Hi

This is a clean backport to jdk25 for updates to the PEM spec.

PEMRecord.pem is renamed to content to better describe that it is the base64 content and not including the header and footer. Additionally, PEMRecord.getEncoded() is removed and some javadoc clarifications for PEMEncoder and PEMDecoder.
Thanks.
