Lazy-load performanceTracker only when performance mode is enabled us…

[swapnachoudhary43]

This PR fixes issue #6418 by implementing lazy-loading of performanceTracker to improve application startup performance.

Changes included:

• Removed the static import of performanceTracker in activity.js so it no longer loads for all users at startup.
• Updated logo.js to dynamically load performanceTracker using RequireJS only when performance mode is enabled.
• Introduced window.performanceTrackerInstance to store the loaded module, replacing all previous typeof performanceTracker !== "undefined" checks.
• Updated all calls to performanceTracker (enable(), disable(), startRun(), enterBlock(), exitBlock(), endRun(), logStats()) to use the new dynamic loading method.

Testing performed:

1. Normal mode (no ?performance=true):

   • performanceTracker.js is not loaded.
   • No console errors related to performanceTracker.

2. Performance mode (?performance=true):

   • performanceTracker.js loads dynamically.
   • All instrumentation functions execute correctly.

Outcome:

• Normal users experience faster startup.

• Performance mode users retain full instrumentation functionality.

• Clean code with no leftover typeof performanceTracker checks ensures maintainability.

• Bug Fix

• Performance

Note: synthutils.test.js is also failing but this is a pre-existing issue on master branch, completely unrelated to this PR. All other 123 test suites pass including logo.test.js.
