DMA EOF may happens per multiple dma descriptors, instead of only one.

Fix #10804 by running continuous ADC DMA in endless loop instead of restarting after each run (descriptor chain) to avoid losing samples. Use descriptor error callback for GDMA to check for DMA buffer overrun.

adc: no longer support adc2 oneshot mode on esp32c3
...
Due to HW limitation, we don't support this anymore. On c3, ADC2 under oneshot mode is not stable.
However, you can enable CONFIG_ADC_ONESHOT_FORCE_USE_ADC2_ON_C3 to force use
ADC2.

adc: no longer support adc2 continuous mode on esp32c3 and esp32s3
...
Due to HW limitation, we don't support this anymore. On s3 and c3, ADC2 under continuous mode is not stable.
However, you can enable CONFIG_ADC_CONTINUOUS_FORCE_USE_ADC2_ON_C3_S3 to force use
ADC2.

adc: fix esp32s2 continuous mode converted bytes issue
...
When working in continuous mode, hardware will continuously trigger
ADC to do conversions. On esp32s2, 2 bytes will be generated per
conversion. Prior to this commit, driver assumes 4 bytes per conversion
(on s2). This commit fixed this issue.
