Write the proguard uuid to the Android manifest

[bruno-garcia]

Description

To avoid reading the sentry-debug-meta.properties at runtime, given that the manifest properties are anyway always read.
Change the plugin so it writes the proguard uuid into the android manifest.

Please note this GHA needs to be amended:

sentry-android-gradle-plugin/.github/workflows/test-publish-dry-run.yaml

Lines 63 to 66 in 2b42432

	cat output/assets/sentry-debug-meta.properties
	rm -r output
	unzip ./examples/android-gradle-kts/build/outputs/apk/release/android-gradle-kts-release-unsigned.apk -d output
	cat output/assets/sentry-debug-meta.properties

Should be done together with #308

Let's come back to this later once we know how many people are actually using the manifest init method.
