19433: cpu/esp32: deduplication in Kconfig for ESP32x SoCs r=aabadie a=gschorcht
### Contribution description
This PR reduces the code duplication in Kconfig for ESP32x SoCs.
It defines a new common CPU symbol `CPU_COMMON_ESP32X` in Kconfig that is used by all `CPU_FAM_ESP32x` symbols. It selects all features, modules and packages that are common for all ESP32x SoC variants. This avoids the selection of features, modules and packages again and again for each ESP32x SoC variant.
The same is done in PR #19432 for common ESP32x board definitions.
