Fix --interpreter flag propagation, add times opcode, fix print/printf LIST context

[fglock]

Summary

• Global interpreter flag: Added FORCE_INTERPRETER (static final) in RuntimeCode.java, checked in both PerlLanguageProvider.compileToExecutable() and EmitterMethodCreator.createRuntimeCode(). Previously, --interpreter / JPERL_INTERPRETER=1 was not propagated to subroutine compilation via createRuntimeCode(), causing 21 JVM-compiled anonymous classes even in interpreter mode.
• times opcode: Added TIMES = 373 with compiler emission, runtime handler (Time.times(ctx)), interpreter dispatch, and disassembly support. Fixes Unsupported operator: times in Benchmark.pm.
• Print/say LIST context fix: CompileBinaryOperator was compiling print HANDLE LIST content in the callers context (often SCALAR). In scalar context, ListNode evaluates all but the last element for side effects only - so print timestr(...), newline called timestr but only printed newline. Fixed by forcing LIST context.
• printf/binmode/seek/eof/close/fileno/getc context fix: Same LIST context issue in compileBinaryAsListOp.

Test plan

• mvn test - all JVM backend tests pass
• JPERL_INTERPRETER=1 ./jperl dev/bench/benchmark_lexical.pl - produces correct timing output
• JPERL_INTERPRETER=1 ./jperl --disassemble - shows only interpreter bytecode, no JVM assembly
• JPERL_SHOW_FALLBACK=1 ./jperl --interpreter - no JVM compilation succeeded messages
• JPERL_INTERPRETER=1 ./jperl -e 'printf "%s %d\n", "hello", 42' - correct output
