8275887: jarsigner prints invalid digest/signature algorithm warnings if keysize is weak/disabled

[GoeLin]

I backport this change from 17u because I had to do adaptions for 17 that
are needed here, too. I needed further fixes, though:

src/java.base/share/classes/sun/security/pkcs/SignerInfo.java
Slight difference in context, change applies to code clean.
I had to change a record to a class to make the change compile
with Java 11.

src/jdk.jartool/share/classes/sun/security/tools/jarsigner/Main.java
Chunks don't apply because in 11 method JAR_DISABLED_CHECK
lacks the prefix JAR_.
checkWeakKey() and checkWeakAlg() are not implemented in 11. Hunk omitted.

test/jdk/sun/security/tools/jarsigner/TimestampCheck.java
Resolved adding bugID to @bug.
