Add *_start and *_running methods to VM_COLLECT_USAGE_DETAILS API

Browse Source 
Add RubyVM::USAGE_ANALYSIS_INSN_START, RubyVM::USAGE_ANALYSIS_OPERAND_START,
and RubyVM::USAGE_ANALYSIS_REGISTER_START to begin collecting VM instructions.

Add RubyVM::USAGE_ANALYSIS_INSN_RUNNING, RubyVM::USAGE_ANALYSIS_OPERAND_RUNNING,
and RubyVM::USAGE_ANALYSIS_REGISTER_RUNNING to check if VM instructions
are being collected.
