This issue was found during the review of this PR: https://github.com/openjdk/jdk/pull/12132 where `Charset` class was loaded/initialized at the phase 1 of the startup process. Since `Charset` depends on `StaticProperty`, loading of `Charset` class should be delayed. I basically moved cache for `jnuCharset` into the actual calling locations `ProcessImpl` and `ProcessEnvironment` for unix platforms so that initPhase1() won't initialize `Charset` class. Unrelated, but I replaced `Locale.ENGLISH` with `Locale.ROOT` in the argument of `toLowerCase()`.
