ddprof TaskBlock bridge and lock-support / object-wait instrumentations

[kaahos]

What Does This Do

• Extends ProfilingContextIntegration with getCurrentTicks, recordTaskBlock, parkEnter, parkExit and wires DatadogProfilingIntegration -> DatadogProfiler -> JavaProfiler.
• Adds lock-support instrumentation (Instrumenter.ForBootstrap): LockSupport.park* / unpark, using bootstrap helpers (LockSupportHelper) for unpark -> park span handoff; parkEnter runs even without an active span so native code can track parked intervals; datadog.TaskBlock emission stays in java-profiler (duration / span gates).
• Adds object-wait instrumentation.
• Registers integration toggles in metadata/supported-configurations.json: DD_TRACE_LOCK_SUPPORT_ENABLED, DD_TRACE_OBJECT_WAIT_ENABLED (defaults true).

Motivation

java-profiler avoids firing wall-clock samples on threads that are clearly idle in sleep or park, and it can emit datadog.TaskBlock events for blocked time. The Java agent has to call the new JNI entry points with timing and span context so those TaskBlock events match real tracing work.

Additional Notes

• linked PR: java-profiler must ship the matching ddprof artifact (JNI + native) before this PR can be merged.
• encode / encodeOperationName / encodeResourceName behavior remains 0 for ddprof (same as prior ProfilingContextIntegration defaults); comment clarifies intent.
• Object.wait: only wait(long) is instrumented, wait() / wait(long, int) route through it on HotSpot.

Contributor Checklist

• Format the title according to the contribution guidelines
• Assign the type: and (comp: or inst:) labels in addition to any other useful labels
• Avoid using close, fix, or any linking keywords when referencing an issue
  Use solves instead, and assign the PR milestone to the issue
• Update the CODEOWNERS file on source file addition, migration, or deletion
• Update public documentation with any new configuration flags or behaviors
