There shall be no special case for inverted PWM pulse when checking
if the captured value is correct.
The output signal inversion is done in HW (at least for stm32h7xx)
SoC. The measured value of the pulse shall be the same - no matter
if we invert the signal or not (as measuring also takes into account
the inversion of the output/input signal).

Without this change the information about PWM polarity is lost when
flags are passed, as the out.flags is set according to PWM description
in the DTS.
For example in: pwms = <&pwm2 2 0 PWM_POLARITY_NORMAL> the out.flags
is always set to PWM_POLARITY_NORMAL.
However, some tests - like 'test_pulse_capture_inverted' require testing
if PWM driver is able to invert the generated signal.
After this change, the generated waveform (from the TIMx pin) is
inverted.
Tested on: Nucleo 'nucleo_h743zi' board (TIM2 ch2 -> out, TIM5 ch1 <- in)

This commit allows testing the PWM (timers) on the
nucleo_h743zi development board.
The HW setup for testing:
Timer2 (channel 2) as PWM signal generator -> CN11 connector
(PIN 30)
Timer5 (channel1) in Capture mode to measure the pulse
duration -> CN11 connector (PIN28)
Such setup allows easy HW loopback connection (just short cut two
consecutive pins/soldering vias on the devel board's PCB).

Add overlay file for disco_l475_iot1 board to pwm_loopback test.
The file is based on the existing overlays for twr_ke18f and frdm_k64f.
The new configuration uses both a 16-Bit timer with active prescaler
as well as a 32-Bit timer with deactivated prescaler for coverage.
It is assumed that other STM32 boards will behave like the
disco_l475_iot1. Only this board was available for testing.

Adds a new zassert to check whether PWM capture has previously been
enabled and correctly returns -EBUSY on a second call.
While working on #39694 this was found to be a missing test case.
The new test case has been verified against the suggested changes of
that PR.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

This is now failing an edtlib check for unknown vendor prefixes.
I can't find a reason to use a vendor prefix in application-local
bindings like this, so just remove it wherever it appears by
normalizing to test-foo-compat instead of test,foo_compat or
test,foo-compat.

Add pinctrl-0 properties for configuration of UART, I2C, SPI, FTM,
DAC, ADC, ACMP, and PWT peripherals. These settings are based on what
is defined in the board/pinmux.c file.
