Summary

Implement five console methods that were previously stubbed as no-ops in the React Native console polyfill:

• console.time(label) - Starts a named timer using high-resolution nativePerformanceNow (with Date.now fallback)
• console.timeEnd(label) - Logs the elapsed time and removes the timer
• console.timeLog(label, ...data) - Logs the elapsed time without stopping the timer, with optional extra data
• console.count(label) - Logs how many times it has been called with the given label
• console.countReset(label) - Resets the counter for the given label

All five methods follow the WHATWG Console spec:

• Default label is "default" when none is provided
• Warnings are logged for duplicate timers, missing timers, and missing counters
• Labels are coerced to strings

Previously, developers using console.time('myOperation') / console.timeEnd('myOperation') for profiling would silently get no output, making it look like the code was never reached. This was a common source of confusion.

Changelog:

[GENERAL] [ADDED] - Implement console.time, console.timeEnd, console.timeLog, console.count, and console.countReset in the console polyfill

Test Plan

Added consoleTimers-itest.js with tests covering:

• Basic timer start/end with elapsed time output
• Default label behavior (uses "default" when omitted)
• Warning on duplicate timer names
• Warning on ending/logging nonexistent timers
• timeLog logging without stopping the timer
• Multiple concurrent timers
• Count incrementing and logging
• Count reset behavior
• Warning on resetting nonexistent counters
• Independent tracking of separate labels
