Resolves#1654
* Update compose and agp in examples

* Fix gradle plugins classloading in examples and templates
* Make falling balls mpp compatible with examples checker
Remove:
```
__LATEST_COMPOSE_RELEASE_VERSION__
__KOTLIN_COMPOSE_VERSION__
System.getenv("COMPOSE_TEMPLATE_COMPOSE_VERSION")
```
They pollute templates/examples.
Now, all paths where we need to change the version are hardcoded in the script.
Usage:
```
./replace.sh 1.0.0-rc6
```
This script is planned to run on CI
In the future I will add support for changing Kotlin version
* Update widgets gallery examples

* Kotlin to 1.5.21.
* Update image viewer example
The build `0.4.0-build182` upgrades
`kotlinx-collections-immutable` library
(which is used by the compose runtime) to 0.3.4,
which was published to maven central,
so most usages of sunsetting jcenter repo
can be removed now.
