Option to ignore non-regressive changes from the baseline

[matejdro]

Currently, Gradle plugin requires stability dump to always be synchronised with the actual Composables in the code, which is a bit of a chore. Ideally, we would want to generate an initial/minimal baseline once and then we would only get alerted when there has been an actual regression in stability.

So, could we get an option to pass stabilityCheck when:

• A composable is removed
• A stable composable is added
• Composable parameters changed, but the new composable is still sable

We would only want the stabilityCheck failing when a change from the baseine resulted in a composable being unstable.

After this is in, there could also be an option to ignore the lack of baseline - even if there is no baseline file present, plugin could still work, it would just always report every single unstable composable in the module (and pass if all are stable).
