Make DeprecatedInNewArchitecture internal (#51201)

Summary:
This class can be internalized as part of the initiative to reduce the public API surface. I've checked there are [no relevant OSS usages](https://github.com/search?type=code&q=NOT+is%3Afork+NOT+org%3Afacebook+NOT+repo%3Areact-native-tvos%2Freact-native-tvos+NOT+repo%3Anuagoz%2Freact-native+NOT+repo%3A2lambda123%2Freact-native+NOT+repo%3Abeanchips%2Ffacebookreactnative+NOT+repo%3AfabOnReact%2Freact-native-notes+NOT+user%3Ahuntie+NOT+user%3Acortinico+NOT+repo%3AMaxdev18%2Fpowersync_app+NOT+repo%3Acarter-0%2Finstagram-decompiled+NOT+repo%3Am0mosenpai%2Finstadamn+NOT+repo%3AA-Star100%2FA-Star100-AUG2-2024+NOT+repo%3Alclnrd%2Fdetox-scrollview-reproductible+NOT+repo%3ADionisisChytiris%2FWorldWiseTrivia_Main+NOT+repo%3Apast3l%2Fhi2+NOT+repo%3AoneDotpy%2FCaribouQuest+NOT+repo%3Abejayoharen%2Fdailytodo+NOT+repo%3Amolangning%2Freversing-discord+NOT+repo%3AScottPrzy%2Freact-native+NOT+repo%3Agabrieldonadel%2Freact-native-visionos+NOT+repo%3AGabriel2308%2FTestes-Soft+NOT+repo%3Adawnzs03%2FflakyBuild+NOT+repo%3Acga2351%2Fcode+NOT+repo%3Astreeg%2Ftcc+NOT+repo%3Asoftware-mansion-labs%2Freact-native-swiftui+NOT+repo%3Apkcsecurity%2Fdecompiled-lightbulb+com.facebook.react.common.annotations.DeprecatedInNewArchitecture).

This class in particular is not in the ReactAndroid.api, so I have the question on whether we should leave these annotations marked as public in case we are already reducing the visibility in another way (and If that's the case, we can close this PR)
