build: Extract shared Android lint config into a build-logic plugin

[runningcode]

📜 Description

Extracts the Android lint configuration that was copy-pasted across the Android modules into a single io.sentry.android.lint convention plugin in build-logic, and applies it to every Android module except the sample.

The shared config is:

lint {
  warningsAsErrors = true
  checkGeneratedSources = true   // new
  checkDependencies = true
  ignoreTestSources = true       // new
  disable += "OldTargetApi"      // centralized from the uitest modules
  checkReleaseBuilds = false
}

Two settings are new relative to the previous per-module blocks:

• ignoreTestSources = true — makes AGP skip creating the test-source lint analysis tasks (lintAnalyzeDebugUnitTest / lintAnalyzeDebugAndroidTest). This is the main speed-up: on sentry-android-core, warm lint dropped from ~4.8s to ~1.8s (~60% faster), since unit-test analysis was the dominant cost.
• checkGeneratedSources = true — avoids false "unused" reports for code used only by generated classes (e.g. ViewBinding), per Tor Norbye's rationale.

Implementation notes:

• AGP is a compileOnly dependency of build-logic, so each module supplies its own AGP at runtime. This keeps the AGP compatibility matrix (8.7–8.9) unaffected — no second AGP copy is bundled.
• The OldTargetApi suppression that previously lived in the two uitest modules is now centralized in the plugin (it's a no-op for library modules, which don't set targetSdk).
• The test/benchmark apps (test-app-plain, test-app-sentry, sentry-uitest-android-critical) carry pre-existing lint issues, so they get lint-baseline.xml files rather than blocking the new strict config. test-app-size lints clean once OldTargetApi is centralized, so it needs no baseline.
• sentry-samples-android keeps its own sample-specific lint config and is intentionally left out.

💡 Motivation and Context

Speed up ./gradlew check lint runs and remove the duplicated lint {} block that was maintained by hand in ~11 module build files.

💚 How did you test it?

Ran lint on every changed module and confirmed all pass, including that the newly-enabled checkGeneratedSources surfaces no new errors and that the baselines filter the pre-existing issues in the test apps. Verified the build-logic plugin configures AGP's lint DSL at runtime with compileOnly AGP and that ignoreTestSources removes the test-analysis tasks across library, KMP (sentry-compose), and application module types.
