Remove vendored code and upgrade to async profiler 4.2

[lbloder]

📜 Description

Upgrade to async-profiler 4.2. This allows us to remove all vendored code from the converter and also adds support for jdk 23+.

💡 Motivation and Context

• Fixes Support Java 23+ in profiler #4853
• Fixes Remove vendored Code from async-profiler #4852

💚 How did you test it?

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

Nice! Left some minor comments.

[adinauer]

We should mention that this means compatibility with newer JDK versions.

[adinauer]

Do we want to remove this again? Or lower log level? I imagine it's quite spammy.

[lbloder]

Ah, yes, oversight on my part. Will remove this

Bug: JFR Reader: Upstream Incompatibility

The code references jfr.javaThreads which was a Sentry-specific modification to the vendored JFR reader but doesn't exist in the upstream one.jfr.JfrReader library. This will cause a compilation error or runtime failure when trying to resolve Java thread IDs from native thread IDs.

sentry-async-profiler/src/main/java/io/sentry/asyncprofiler/convert/JfrAsyncProfilerToSentryProfileConverter.java#L118-L123

sentry-java/sentry-async-profiler/src/main/java/io/sentry/asyncprofiler/convert/JfrAsyncProfilerToSentryProfileConverter.java

Lines 118 to 123 in c6df8f0

	private long resolveThreadId(int eventId) {
	Long javaThreadId = jfr.javaThreads.get(eventId);
	return javaThreadId != null ? javaThreadId : UNKNOWN_THREAD_ID;
	}
	private void processThreadMetadata(Event event, long threadId) {
