Trunk 6514 performance markers

[YO-WHATS-UP2]

Description of what I changed

In this pull request, I have introduced SLF4J performance markers to the log.debug statements that were originally added in TRUNK-6436 to monitor OpenMRS startup performance. This change allows developers and system administrators to easily filter or redirect performance-related logs by targeting the "performance" marker.

The following changes were implemented:

• Created a reusable PERFORMANCE_MARKER using MarkerFactory.getMarker("performance") in multiple core and web classes.
• Updated logging calls to include the marker in ModuleUtil.java, WebModuleUtil.java, Listener.java and InitializationFilter.java.
• Verified that all strings are parameterized to follow OpenMRS logging best practices.
