Be compatible with Android 12 permissions and build on M1 Mac

[MrCsabaToth]

This will need the upgrade of these plugins at least:

• bluetooth_enable
• flutter_blue
• permission_handler

First as a quick start I'll:

• depend on bluetooth_enable_fork instead of bluetooth_enable, although later possibly I have to bring-in custom changes into my own fork
• depend on boskokg's fork (https://github.com/boskokg/flutter_blue), and later possibly reintroduce my pac-man exception catches in an own fork to get rid of release-only crashes
• unpinned the permission_handler version so it could be upgraded to the latest

With this flutter upgrade only sees 7 transitional dependencies it could not upgrade.
I opened the android12_and_m1 feature branch for this but haven't tested it yet.

Research for #16 has related findings!

Note that the boskokg fork has features which may make bluetooth_enable unnecessary, like this one displays permissions for iOS pauldemarco/flutter_blue#964

The end is near. Now Flutter SDK 2.10.1 has a new feature, during build I'm warned:

Warning: The plugin flutter_plugin_android_lifecycle requires Android SDK version 31.
Warning: The plugin integration_test requires Android SDK version 31.
Warning: The plugin package_info_plus requires Android SDK version 31.
Warning: The plugin path_provider_android requires Android SDK version 31.
Warning: The plugin shared_preferences_android requires Android SDK version 31.
Warning: The plugin soundpool requires Android SDK version 31.
Warning: The plugin url_launcher_android requires Android SDK version 31.
One or more plugins require a higher Android SDK version.
Fix this issue by adding the following to /home/csaba/repos/flutter/track_my_indoor_exercise/android/app/build.gradle:
android {
compileSdkVersion 31
...
}

Looks like for M1 Android a protobuf version is important pauldemarco/flutter_blue#947 (comment)

Note: Sebastian's find: unleash dependabot once we can unpin BLE/permission related packages https://github.blog/changelog/2022-04-05-pub-beta-support-for-dependabot-version-updates/
