Feature / Added baseline and startup profile generation

[LinX64]

This uses the proper task for the NightlyBaselineProfiles build script.

1. First, it sets up the GMD and creates a snapshot
2. Generates the baseline profile and startup using :app:generateReleaseBaselineProfile

Two steps were missing in the current script.

@keyboardsurfer @dturner - Would appreciate your thoughts on this.

@keyboardsurfer Unfortunately, I couldn't test this on this repo as it requires some approvals. But in case you wanted to see how that might behave, here is a sample: https://github.com/LinX64/Baseline

Baseline Profiles do not need to be part of the repository's source code. We have chosen to only generate BP for release builds (and as nightly as continuous check that nothing is broken). Over time this saves a lot of data when checking out the repository.

I understand the reason why you kept it like that, so thanks. However, I should say that the NightlyBaselineProfiles script does not properly check for the purpose you mentioned.

For this purpose, I'd have:

- name: Generate Baseline Profile
        run: ./gradlew :app:generateReleaseBaselineProfile
          -Pandroid.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=baselineprofile
          -Pandroid.testoptions.manageddevices.emulator.gpu="swiftshader_indirect"
          --stacktrace

To verify if everything works as expected.
