Fix release default options visibility (#441)

* Update README.md for 1.5.0-alpha-2 release.

* Fix release option default visibility

* Move default options to kt_configure_toolchains for a single source of truth
Limit kt_configure_toolchains to kotlin/internal as it defines the toolchain_type which is a well known target. Configuring them elsewhere could have unexpected issues.
Move the kt_configure_toolchains out of jvm. (I'm pretty sure I did that, and it's just wrong.)
