  QMX: add SWR and RF power meter readback

The QMX backend defined no .get_level, so rig_get_level(RIG_LEVEL_SWR)
returned -RIG_ENAVAIL. QRP Labs firmware provides the readings as
extensions on top of the TS-480 command set:

  SW; returns SWR in hundredths      (SW121; = 1.21:1)
  PC; returns output power in tenths (PC45;  = 4.5 W)

Both are transmit-only. In receive the QMX answers with a bare SW; /
PC;, reported as 0 rather than a stale value. RFPOWER_METER is scaled
against 5 W for the 0.0..1.0 form.

level_gran_kenwood.h gains NO_LVL_SWR / NO_LVL_RFPOWER_METER_WATTS
guards, following the existing NO_LVL_KEYSPD pattern, so the QMX can
declare its own resolution.

Tested against a QMX running firmware 1_04_003QMX.

  QMX: read power meter full scale from the radio

QMX_MAX_POWER was hardcoded to 5.0f, taken from the "5W class radio"
description. That is not the figure the hardware meters against: the
QMX power meter full scale is a user setting, 6W on a stock radio and
12W on one carrying the PA0RDT 4+4 BS170 PA modification. A stock QMX
at full output therefore reported RFPOWER_METER as 1.2 rather than 1.0.

The radio will say which it is, via the Menu Manager command:

  MMDisplay/controls|Pwr/SWR display|Power fullscale;   ->   MM6W;

qrplabs_qmx_open wraps qrplabs_open (which stays shared with the
QCX/QDX caps) to probe it once and keep the answer in
level_gran[LVL_RFPOWER_METER_WATTS].max, which is both where the value
belongs and where get_level can find it again -- no extra field in the
shared kenwood_priv_data. rig_init copies level_gran out of caps long
before caps->rig_open runs, so the override sticks.

The probe is optional, so question_mark_response_means_rejected is set
across it, following ts590.c. Firmware predating MM answers "?;" and
would otherwise burn the full retry budget on every open; instead it
fails immediately and the 6W default declared in the caps stands.

RFPOWER_METER_WATTS is unchanged -- PC; returns absolute watts, and the
full scale setting only ever scaled the front panel bar graph.

Tested against a QMX running firmware 1_04_005QMX, which reports 6W.
The 12W branch is untested for want of a modified radio.
