RFR: 8359732: Make standard i/o encoding related system properties `StaticProperty`

[Naoto Sato]

Refactored the internal handling of `stdin/out/err.encoding` to allow setting them only via command-line options by converting them into `StaticProperty`. This change prevents unexpected behavior caused by applications modifying these properties at runtime using `System.setProperty()`.
