Fix the crash caused by ButtonCompositionGroupMapper when calculating the corner radius

Motivation

A crash is found when I test with an Android open source application,

here is the trace:

 java.lang.IllegalStateException: Size is unspecified
       at androidx.compose.ui.geometry.Size.getWidth-impl(Size.kt:48)
       at androidx.compose.ui.geometry.Size.getMinDimension-impl(Size.kt:128)
       at androidx.compose.foundation.shape.PercentCornerSize.toPx-TmRCtEA(CornerSize.kt:100)
       at com.datadog.android.sessionreplay.compose.internal.mappers.ButtonCompositionGroupMapper.map(ButtonCompositionGroupMapper.kt:42)
       at com.datadog.android.sessionreplay.compose.internal.mappers.AbstractCompositionGroupMapper.map(AbstractCompositionGroupMapper.kt:37)

Demo

In the demo we can see the corner radius of the button is correct

In which cases can a CornerSize be a percentage (or not)?

[ambushwork]

It totally depends on the choice of our clients (app developers) how they want to implement UI, either they can use a corner with specific dimension size, so no matter what the size of the button is, the corner keeps same. Either they can use percentage like I show in the screenshot, so the corner radius adapt with button size.

In this case, we must support both of them.

Good catch
