refactor: Convert constants SentrySpanOperations to Swift

[philprime]

📜 Description

Collects all global constants defined in SentrySpanOperations.h and other various variables into static constants in a Swift class

💡 Motivation and Context

• We want to migrate the code base to Swift over time
• We want the constants to be available in Swift without complicated setup
• Span operation names are defined in the Sentry specification and should be managed in one spot to match the spec
• It uses a @objcMembers class to make the static properties accessible from Objective-C.
• The current pattern uses the same syntax as Swift's enum which is not available in Objective-C. Eventually it will only be used from Swift files, and can be replaced with an enum without further code changes.

💚 How did you test it?

CI tests

📝 Checklist

You have to check all boxes before merging:

• 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 👍🏻

I would like to keep the constants internal if possible.
