RFR: 8287764: runtime/cds/serviceability/ReplaceCriticalClasses failed on localized Windows

[KIRIYAMA Takuya]

The ReplaceCriticalClasses verifies CDS behavior when replacing the Readable interface as an example of a class that is read after JVMTI_PHASE_PRIMORDIAL.
However, the order in which classes are loaded is affected by the language of the test environment, so the timing at which the Readable interface is loaded also changes on Windows with multibyte characters.
Therefore, the Readable interface is not suitable for this test and should be removed.
