arch/xtensa: add support for capture driver on ESP32 and ESP32|S3|
Squashed: Initial settings for MCPWM Capture on board level Created lower half files - compilation ok Using capture debug features. Simple example on fops works Successful duty and freq calculation Documentation update Fixed and added interupt capabilities for all 3 capture channels Cleaned defconfig Renamed macros, added S3 options and moved arch source to common dir Added support for ESP32S3 Added capture example to defconfig and renamed
