cpu/atmega_common: Make GPIO_DISCONNECT alias for GPIO_INPUT 
Since on ATmega GPIOs cannot be disconnected and the reset state is
them being an input, this may help making code more portable.

drivers/periph/gpio_ll: pass gpio_conf_t by value 
Now that `gpio_conf_t` is on all implemented platforms no larger than
a register, we can more efficiently pass it by value rather than via
pointer.

drivers/periph/gpio_ll: shrink gpio_conf_t 
This commit optimizes the `gpio_conf_t` type in the following
regards:

- The "base" `gpio_conf_t` is stripped from members that only some
  platforms support, e.g. drive strength, slew rate, and disabling of
  the Schmitt Trigger are no longer universally available but
  platform-specific extensions
- The `gpio_conf_t` is now crammed into a bit-field that is 8 bit or
  16 bit wide. This allows for storing lots of them e.g. in
  `driver_foo_params_t` or `uart_conf_t` etc.
- A `union` of the `struct` with bit-field members and a `bits` is used
  to allow accessing all bits in a simple C statement and to ensure
  alignment for efficient handling of the type

783afbc666 cpu/avr8_common: Add AVR8_ISR macro 
The current ISR implementation for AVR8 requires use of
avr8_[enter/exit]_isr pair which add some boilerplate on code.
This add AVR8_ISR which clean-up the code and make it simpler
and hides any schedule detail from the user perspective.

This is a preparation for future scheduling and irq optimizations.

b7873015aa cpu/avr8_common: Split avr8_state 
The avr8_state store state information used to determine scheduling
and uart irq. This move all uart irq states to avr8_state_uart
variable. It introduce the use of General Purpose IO Register 0
(GPIOR0) when available and now all uarts from xmega can be used.

This is a preparation for future scheduling and irq optimizations.

Merge #19752 
19752: cpu/atmega_common: checking features instead of CPU models r=benpicco a=hugueslarrive

### Contribution description
Splitted from:
- #19740

### Testing procedure
Tested on atmega8 with:
- #19755

This one probably need to be tested on others cpu.
### Tests on 1284p:

2023-06-22 19:01:26,900 # This application is intended for testing additional UART
2023-06-22 19:01:26,900 # interfaces, that might be defined for a board. The 'primary' UART

2023-06-22 19:01:26,902 # data will be outputted via STDIO. So the easiest way to test an 
2023-06-22 19:01:26,903 # UART interface, is to simply connect the RX with the TX pin. Then 
2023-06-22 19:01:26,904 # you can send data on that interface and you should see the data 
2023-06-22 19:01:26,904 # being printed to STDOUT

cpu/atmega_common: make vera++ happy 
Vera++ doesn't like `#error` preprocessor directives without a quoted
string afterwards (and also my syntax highlighter doesn't like this as
well). So let's add the quotes to have the tools not spooked out.

cpu/atmega_common/periph/pwm: Minor fix & cleanup 
- On pwm_poweron, the PWM resolution was not restored. (A custom resolution was
  only usable if, PWM channel 0 is not used. That configuration is not common,
  so this bug was likely never triggered)
- Disabled a work around to prevent flickering:
    - Previously, PWM was disconnected on level 0% and 100%
    - This increases the run time of `pwm_set()`
    - It prevents using the PWM for wave form generation via DDS, as the wave
      noticeably jumps when reaching 0% or 100%
- Slightly reduces memory requirements: 2 Bytes of RAM, 112 Bytes of ROM
    - Tested with avr-gcc 9.2.0 and LTO enabled

93d2068a9e cpu/atmega_common: Implement RTC based on TIM2 
This implements a basic Real Time Clock based on TIM2.

As the timer is too fast and wraps around after just 8 bits, it is
not used directly. Instead TIM2 is responsible for providing a 1 Hz
tick by generating an alarm every second.

The current time data is kept in the `.noinit` section, so it will survive
a reboot, but the clock will not be updated while the bootloader runs, so
expect inaccuracies.
