[jdk11u-dev] RFR: 8140466: ChaCha20 and Poly1305 TLS Cipher Suites

[Alexey Bakhtin]

This backport adds ChaCha20 cipher suites to 11u implementation for TLSv1.3 and TLSv1.2 protocols.
TLS_CHACHA20_POLY1305_SHA256 is one of the cipher suites SHOULD be implemented according to rfc8446 [1].

The original patch applies almost clean except for the test/jdk/javax/net/ssl/TLSCommon/CipherSuite.java file - the list of cipher suites was reordered by JDK-8210632 [2]

Also, I had to update two jtreg tests with ChaCha cipher suites:
test/jdk/javax/net/ssl/sanity/ciphersuites/CheckCipherSuites.java is updated because of JDK-8217579 [3] backport to 11u missed CHACHA20 cipher suites

test/jdk/javax/net/ssl/sanity/ciphersuites/CipherSuitesInOrder.java is updated because of JDK-8234728 [4] backport to 11u missed CHACHA20 cipher suites

sun/security/ssl and javax/net/ssl tests passed
