fe90c49795 fix/feat(stm32/russell): Serial2 build fix and BME680 support (#10097)
* fix(stm32/russell): define ENABLE_HWSERIAL2 and Serial2 pins

The Russell board variant was missed during Initial serialModule cleanup
(PR #9465), which began requiring Serial2 to be explicitly defined via
ENABLE_HWSERIAL2 and PIN_SERIAL2_TX/RX rather than relying on implicit
defaults, causing a build error.

* feat(stm32/russell): add BME680 support, exclude modules to fit flash

The BME680 is hardware footprint compatible with the BME280 already
present on the Russell board, so add it as an additional lib dep to
enable environment sensing (temperature, humidity, pressure,
gas resistance).

The STM32 target has very limited flash. Even traceroute alone causes
overflow, so the following modules are excluded to stay within budget:

  - RANGETEST
  - DETECTIONSENSOR
  - EXTERNALNOTIFICATION
  - POWERSTRESS
  - NEIGHBORINFO
  - TRACEROUTE
  - WAYPOINT

AIR_QUALITY_SENSOR is also excluded as it requires the BSEC2 library
for real IAQ output, which alone overflows flash by ~44KB on this
target. The Adafruit BME680 library is used instead for raw sensor
readings.
