ref: Remove unnecessary @objcMembers and @objc annotations

[github-actions]

Note

The pull request "ref: Remove unnecessary @objcMembers and @objc annotations" was created by @noahsmartin but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

• Remove @objcMembers from SentryViewRendererV2 and SentryDefaultViewRenderer as they are not used from Objective-C code (only conform to @objc protocol)
• Make SentryViewRendererV2 and SentryDefaultViewRenderer internal since they are implementation details not exposed in the public API
• Remove @objcMembers from SentryANRStoppedResult as it is only used from Swift
• Remove redundant @objc from SentryLog since @objcMembers already exposes the class to Objective-C
