Since parcelize is Android specific, it should only be enabled for
Android compilation. In order to allow parcelize to generate code
for declarations in common code, we make checkers platform checkers
and we allow the registration of an additional annotations to
trigger parcelize processing.
That way, code such as:
```
package my.package
annotation class Parcelize
expect interface MyParcelable
@Parcelize
data class User(name: String): MyParcelable
```
Will work with an Android platform actual of the form:
```
actual typealias MyParcelable = android.os.Parcelable
```
And telling the plugin to trigger parcelize processing with the
additional annotation `my.package.Parcelize`.

This commit adds support for the Parcelize plugin to generate default
serialization implementation for the kotlin.time.Duration. As Parcelize
already supports serializing some of the kotlin library types it makes
sense to support more common ones for the user convenience.
