This commit multiple issues with the following RMT TX tests:
- rmt_multi_channels_trans_no_dma
- rmt_multi_channels_trans_with_dma
The following issues are fixed:
- Channel stop times are now tested using TEST_ASSERT_INT64_WITHIN(). The
previous method did not account for the case where channel 1 finished before
channel 0
- Increased synchronous stop time delta for esp32-c6
- Increased main task stack size to prevent stack overflow onesp32-s3
