refactor mcux sar adc driver

[ZhaoxiangJin]

1. This PR refactors the mcux sar adc driver. Zephyr's current ADC API only supports 32 logical channels, which is inadequate for SAR ADCs on certain SoCs. For instance, the ADC on the MCXE31B has 64 hardware channels. The previous implementation used a one-to-one mapping between logical and hardware channels. In the new SAR ADC driver version, we bind hardware channels to logical channels via the zephyr,input-positive property, enabling us to access any channel. Currently, only imx93 uses this ADC. To maintain the bisectability of Zephyr commits, the refactored code and imx93-related file updates are placed in the same commit. The migration-guide-4.4.rst has also been updated accordingly to document this change.
2. Now the sar adc is native driver, so, remove CONFIG_MCUX_COMPONENT_driver.sar_adc from the glue cmake.
3. Enabled sar adc for mcxe31b platform.
4. Enabled adc samples for frdm-mcxe31b.
