Kotlin to 1.8.0 and JDK Toolchain to 11 (#37220)

Summary:
Pull Request resolved: facebook/react-native#37220

I'm bumping Kotlin to 1.8.0 to align to the version used internally.

On top of this, I had to configure the JDK toolchain to 11 as Kotlin 1.8
was changing the default version of the stdlib it ships with by default.

This also shields us against problems once we'll bump to AGP 8 which requires
JDK 17 but still allows to produce libraries that are JDK 11 compatible.

Changelog:
[Android] [Changed] - Kotlin to 1.8.0 and JDK Toolchain to 11
