Related to #149836
- Remove last usages of minSdkVersion/compileSdkVersion/targetSdkVersion
in favor of minSdk/compileSdk/targetSdk. That do not also use
`flutter.minSdkVersion` etc. (that will happen in another pass)
- Update the files that used "SdkVersion" to use equals for setting new
values. [Not yet landed documentation
change](https://github.com/flutter/flutter/pull/164195/files#diff-ee6ec18be8d752e2696c8ccc8bec2f202dfc29a43b3b4f9d8041aa6bc3e852a1)
- align sourceCompatibility and targetCompatibility across repo to use
JavaVersion.* and update android version documentation.
This pr updates `kotlinOptions jvmTarget` documentation but does not fix
all existing usages.
This pr is expected to cause no behavioral changes.
This pr makes logical sense after
https://github.com/flutter/flutter/pull/164195 but can be landed in any
order.
