modules: sensor: add warmup delays to prevent CCS811 early read failures

[nmpluta]

This pull request adds support for configurable sensor warmup periods in the sensor module, allowing certain sensors to stabilize before their readings are used. The changes include new Kconfig options for enabling warmup and setting warmup durations per sensor, as well as logic in the sensor state machine to track and enforce warmup completion before reading or publishing sensor data.

Sensor warmup configuration and logic:

• Added new Kconfig options in Kconfig.sensor to enable sensor warmup (SENSOR_MODULE_WARMUP_ENABLE) and specify warmup durations for CCS811, BME280, and HM3301 sensors (SENSOR_MODULE_CCS811_WARMUP_MS, etc.).
• Extended the sensor_state_object in sensor_module.c to track initialization time and per-sensor warmup completion status when warmup is enabled. [1] [2]
• On initialization, now records the startup time and resets warmup completion flags for all sensors.

Sensor reading and state machine updates:

• Modified the reading logic to skip sensors that have not completed their warmup period, and to only count sensors as enabled if their warmup is done. [1] [2]
• Added helper functions to check warmup status and compute elapsed warmup time for each sensor, marking sensors as ready when their configured warmup period has passed. [1] [2]

Fixes: #16

Pull Request Overview

This PR adds configurable sensor warmup periods to prevent early read failures, particularly for CCS811 sensors that require stabilization time after initialization. The implementation includes new Kconfig options for warmup configuration and state machine logic to track and enforce warmup completion before reading sensor data.

• Adds Kconfig options for enabling sensor warmup and configuring warmup durations per sensor type
• Extends sensor state machine to track initialization time and warmup completion status
• Modifies sensor reading logic to skip sensors that haven't completed warmup and handle partial reads gracefully
