Drop legacy SLF4J providers/bridges and add explicit exclusions to prevent log4j-slf4j-impl and slf4j-simple/reload4j from reappearing transitively.

Switch to MarkerFactory for query-complete markers so LLAP builds cleanly with SLF4J 2.x provider-only bindings. Co-authored-by: Cursor <cursoragent@cursor.com>

What changes were proposed in this pull request?
I've upgraded the logging infrastructure from SLF4J 1.7.x to 2.0.13.
Since SLF4J 2.x moves from static binding to a ServiceLoader architecture, I realigned the bridges to prevent "silent" logging failures. Key changes include:
Updating slf4j-api, slf4j-reload4j, and jcl-over-slf4j to 2.0.13 across the root, standalone-metastore, and storage-api.
Switching the Log4j2 bridge to log4j-slf4j2-impl (2.24.3) to ensure Hive's internal metrics and timing systems can communicate with the new API.
Why are the changes needed?
Security: Resolves several CVEs associated with the older 1.7.x line.
Stability: Modernizes the logging backend and fixes "NOP" (No-Operation) logger errors that were causing metrics and audit logs to be dropped silently.
Does this PR introduce any user-facing change?
No. This is a backend dependency and architectural alignment.
How was this patch tested?
Dependency Audit: Verified via mvn dependency:tree that all modules have converged on 2.0.13 with no legacy 1.7.x bindings remaining.
Unit Tests: Confirmed that logging-dependent tests (e.g., TestAtlasLoadTask, TestHiveRemote, and TestOperationLogManager) are passing, specifically verifying that metrics and API timing strings are correctly captured.
Build Integrity: Passed a clean local build to ensure no compilation regressions in ql or service modules.
