trace: [tcg] Define TCG tracing helper routine wrappers

Browse source 
Generates header "trace/generated-helpers-wrappers.h" with definitions for TCG
helper wrappers.

These wrappers ('gen_helper_trace_${event}_exec_wrapper') transform mixed native
and TCG argument types to TCG types and call the actual TCG helpers
('gen_helper_trace_${event}_exec_proxy').
