[RORDEV-1941] Do not apply JDK patch, remove ROR <=1.64 fallbacks

[mgoworko]

The JDK patch related to https://bugs.openjdk.org/browse/JDK-8287073 no longer needs to be applied since ROR 1.69. Removing also patching-related args for ROR<1.64

Summary by CodeRabbit

• Chores

  • Reduced environment bootstrap time by pre-pulling runtime images and removing the prior local Elasticsearch JDK-patch build.
  • Simplified image selection to derive runtime images from configured repository/version values.
  • Reordered startup to create the local cluster earlier and apply required kernel settings to nodes before continuing.

• Bug Fixes

  • Consolidated patch-consent setting to a single environment variable for clearer configuration.
