Compose Modifier
windowInsetsStartWidth
Common
```kotlin
fun Modifier.windowInsetsStartWidth(insets: WindowInsets) =
this then
DerivedWidthModifierElement(
insets,
debugInspectorInfo {
name = "insetsStartWidth"
properties["insets"] = insets
},
startCalc,
)
```
Sets the width to that of `insets` at the `start` of the
screen, using either `left` or `right`, depending on
the `LayoutDirection`.
When used, the `WindowInsets` will respect the consumed insets from
`windowInsetsPadding` and `consumeWindowInsets`, but won't consume any insets.
