stm32wl: exclude PKT_HISTORY_HASH, RANGETEST, WAYPOINT, POWER_TELEMETRY (#10992)

Adds four MESHTASTIC_EXCLUDE_* flags to stm32_base, applying them to
every stm32wl variant (rak3172, wio-e5, russell, milesight_gs301,
CDEBYTE_E77-MBL):

- PKT_HISTORY_HASH: mirrors the accepted nRF52 precedent
  (variants/nrf52840/nrf52.ini) - drops PacketHistory's hash index;
  the O(n) fallback is negligible given stm32wl's small node table.
  No feature loss.
- POWER_TELEMETRY: only affects external power-monitor ICs
  (INA219/INA260 etc.) via PowerTelemetryModule; internal battery ADC
  reading (src/Power.cpp) is a separate, ungated code path and is
  unaffected. No current stm32wl variant wires up external
  power-monitor hardware.
- RANGETEST: real feature loss on wio-e5 specifically, the only
  stm32wl variant with GPS enabled (RangeTest requires GPS to run at
  all, so it was already dead on every other variant).
- WAYPOINT: real feature loss on rak3172/wio-e5 (russell already
  excluded this individually; that duplicate is removed here since
  stm32_base now covers it).

Measured on wio-e5 against upstream/develop @ 7a25ffd0a: 2,768 bytes
flash saved (240,648 -> 237,880), 260 bytes RAM saved. Sanity-built
russell and rak3172 to confirm no regressions from the russell
dedup.
