Fix Handle null context in Baggage.fromContext() and Baggage.fromContextOrNull()

[NithinU2802]

In Baggage, to add null checks to Baggage.fromContext(context) and Baggage.fromContextOrNull(context) with log using ApiUsageLogger and for Baggage.fromContext(context) now returns empty() when the context is null, also for Baggage.fromContextOrNull(context) returns null. Additionally, added unit tests to cover these scenarios.

I'm happy to update any changes if needed.

Closes #8665

Small inconsistency here: this passes Context.class while fromContext above passes Baggage.class. Span.fromContextOrNull uses the declaring class too, and since the message is built from it, users would see a warning naming Context.fromContextOrNull, which isn't a real method on Context.

Suggested change

	ApiUsageLogger.logNullParam(Context.class, "fromContextOrNull", "context");
	ApiUsageLogger.logNullParam(Baggage.class, "fromContextOrNull", "context");

[NithinU2802]

yeah, that's correct had updated from Context to Baggage.

[abdessattar23]

The issue lists the ApiUsageLogger output as part of the expected behavior, but the test only asserts return values. Adding a LogCapturer assertion on the api usage logger would cover it, and would have caught the Context.class / Baggage.class mismatch above. Minor: might read better split into fromContext_null and fromContextOrNull_null.

[NithinU2802]

I have split tests into fromContext_null and fromContextOrNull_null also added LogCapturer to verify the ApiUsageLogger output✌️

[abdessattar23]

LGTM, both points addressed. Needs a maintainer's sign-off though, I'm just a fellow contributor, not a code owner

@jack-berg can do the rest
