Update Liberty code to call Java API KeyManager.chooseEngineClientAlias() per each key type

[una-tapa]

Describe the bug
In WSX509KeyManager class, Liberty is only trying the first keyType : keyType[0]

Steps to Reproduce
The user updated Java from 17.0.9 to 17.0.11. It is suspected that in the user's environment, the keyType array in 17.0.9 coincidentally started with a keyType matching the certificate, whereas this is not the case in 17.0.11.

Expected behavior
Liberty locates and sends a SSL client certificate correctly to the SSL server during SSLHandshake

Diagnostic information:

• OpenLiberty version: This issue is not related to the OpenLiberty version
• Affected feature(s) transportSecurity-1.0, ssl-1.0
• Java Version: Java 17 (Currently investigating)
• server.xml configuration This issue is not related to a certain configuration

For GOOD log, WSX509KeyManager.chooseEngineClientAlias() finds a matching alias for RSA.

For ERROR log, WSX509KeyManager.chooseEngineClientAlias() finds no matching alias for [EC, EdDSA, RSASSA-PSS, RSA, DSA] when passed all at once.
