The InfraredRFReceiveEvent encode benchmark used a C++17 lambda IIFE
(`[]{...}()`) to seed a function-static vector, and the
InfraredRFTransmitRawTimingsRequest decode benchmark grew its APIBuffer
one byte at a time (~210 grow_() calls), each allocating a fresh
exact-fit buffer and memcpy'ing the prior contents. Both patterns are
fine under direct execution but appear to hit a CodSpeed/valgrind
edge case during the simulated benchmark run.
Switch to a plain heap-init pattern for the vector and build the wire
bytes into a stack array first, then resize+memcpy into the APIBuffer
once.
Mirrors the existing BluetoothLERawAdvertisementsResponse benchmarks for
the remaining proxy message families: ZWaveProxyFrame/ZWaveProxyRequest,
SerialProxyDataReceived/SerialProxyWriteRequest, and
InfraredRFReceiveEvent/InfraredRFTransmitRawTimingsRequest.
Adds minimal stub headers under tests/benchmarks/stubs/ for the
zwave_proxy, infrared, radio_frequency, and serial_proxy components so
api_connection.cpp compiles without dragging in their UART/RMT/BLE
hardware dependencies.
