RFR: 8305955: Remove Visual C++ specific workaround in javac [v2]

[Julian Waters]

> Visual C++ no longer requires the use of the i64 literal syntax and instead recommends the use of LL instead, so we should remove this workaround in the JNIWriter (this also helps when users write Windows JNI code meant to be compiled with alternate compilers other than Visual C++)
