Loading Wheel flexible number of lines

[JackEblan]

Thanks for submitting a pull request. Please include the following information.

What I have done and why

The number of lines in Loading Wheel is set to 12 and there is no way to change this because the rotate degrees for each line drawn is hard-coded to rotate(degrees = index * 30f)

How I'm testing it

Choose at least one:

• Unit tests
• UI tests
• Screenshot tests
• N/A (provide justification)

Do tests pass?

• [x] Run local tests on DemoDebug variant: ./gradlew testDemoDebug
• [x] Check formatting: ./gradlew --init-script gradle/init.gradle.kts spotlessApply

Is this your first pull request?

• [x] Sign the CLA
• [ ] Run ./tools/setup.sh
• [ ] Import the code formatting style as explained in the setup script.

What situation we need to customize the rotationTimeInMillis and numberOfLines?

[JackEblan]

By making this loading composable customizable like:

• trackThickness
• indicatorColor
• trackColor
• indicatorInset
• indicatorDirectionCircular This is from Jetpack Compose progress indicator

This is a great contribution, but I don't think this will ever be merged. Providing a customizable design system is definitely not the primary goal of this project.
