For STM32H7, U5 and WBA, check the LDORDY bit of the ADC ISR register
after enabling the internal regulator. This method is safer than the
delay.

Burst mode enabled on an unused channel causes a freeze during a
conversion consisting of several channels (not including the one with
burst mode enabled).
Discovered on nRF52832 (nRF52-DK) using the following approach:
channels 0-3 are used for application purposes as a sequence
channel 4 is used for battery measurements with oversampling
After few successful conversions the sequence (channels 0-3) freezes the
thread while waiting for semaphore to end the conversion.

The AD5593 conversion result also contains the channel read and not just a
value:
| adc channel (3 bits) | adc value (12 bits) |
This value was not removed from the result before using it as an adc value.

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

k_thread_name_set() function returns an error if CONFIG_THREAD_NAME is
not enabled which may make the driver not functional.
Fix the issue by adding a check against CONFIG_THREAD_NAME avaliability
before calling k_thread_name_set() function so the driver can operate
properly with CONFIG_THREAD_NAME disabled.

Several STM32 variants include both shared IRQs for some ADCs and
separate IRQs for others (for example, STM32G473 has 5 ADCs, ADC1 and
ADC2 share one IRQ while ADC3, ADC4 and ADC5 each have unique
IRQs). The STM32 ADC driver however previously only supported either
separate IRQ lines for each operational ADC in the devicetree or a
single shared IRQ for all operational ADCs in the devicetree which
prevented all ADCs from being usable at the same time when the variant
contained a mix of both shared and separate ADC IRQ lines (only either
all the shared or all the separate and one of the shared might be used
at most for one application).
To allow for all ADCs in an STM32 variant to be usable in a single
application, generate an ISR and initialization function for each
unique IRQn as defined in the devicetree and give the task of
initialization to the first ADC which connects to that particular
IRQ. Each ISR function will generate code to call the ISR for each ADC
associated with that IRQn as was previously done for
CONFIG_ADC_STM32_SHARED_IRQS, allowing an ISR to be shared for the
ADCs sharing an IRQ while simultaneously providing separate ISRs for
each IRQ. Thus, the only information required to have ADCs either
share an ISR or not is provided by the devicetree.
