[jdk11u-dev] RFR: 8340321: Disable SHA-1 in TLS/DTLS 1.2 handshake signatures

[Antonio Vieiro]

Backport of [JDK-8340321](https://bugs.openjdk.org/browse/JDK-8340321) from [JDK17](https://github.com/openjdk/jdk17u-dev/commit/86765246d95c9e9586540c5f865ba093dff92ffe), that [disables SHA-1 in TLS/DTLS 1.2 handshake signatures](https://www.java.com/en/configure_crypto.html#DisableSHA1_TLS_DTLS) to comply with the [Oracle JRE Cryptographic Roadmap](https://www.java.com/en/jre-jdk-cryptoroadmap.html).

Backport is not clean, as there many differences in `java.security` from 17 to 11.

Tested with `tier1` tests on Linux and with `run-test-jdk_security`, that includes the new three new tests:
