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.

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:

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: Clean up PCINT support
- Using a enum instead of _COUNTER is easier to read
    - _COUNTER is also a reserved name; so better not use it to avoid issues
- Split out the pcint code into a static inline function for increased
  readability

cpu/atmega_common/periph: Fixed bug in PCINT
The bank index and the pin number are not necessarily identical. For all
PCINT banks except for bank 3 bank_idx was used therefore. It was likely
just forgotten to update that for bank 3 as well.

cpu/atmega_common: Stop using reserved names
Names with two leading underscores are reserved in any context of the c
 standard, and thus must not be used. This ATmega platform used it however for
 defining internal stuff. This commit fixes this.

cpu/atmega_common: Restructured code

to cpu/atmega_common/include/atmega_gpio.h in order to reuse them for the
platform specific low level part of the Neopixel driver.

d9aac6a7d4 atmega_common/gpio_init: fix pull-up settings for GPIO_IN_PU
This Patch makes gpio_init precalculate the pin mask once,
This Patch makes gpio_init of atmega_common configure the pin as an input and configure the pullup in the case of GPIO_IN_PU.
GPIO_IN_PU and GPIO_IN need to change pullup so they need to change output (this is coverd by the not touching outputs is not guaranteed statement)
(this is a special case for atmega the pull_up is configured by writing 1 to the port_register which is also the level of the output if the pin is configured to output).

This fix makes it more compliant to comments in periph/gpio.h

3ad71d5be0 atmega_common/gpio.c Fixes GPIO interrupt
fixes the GPIO_LOW interrupt on the atmega platform.
It results from trying to shift GPIO_LOW. Since it is 0, it is not shiftable and will not be set correctly.
There were more issues with the other flanks too, as they are 0b01 or 0b00. If 0b11 was set as a flank before it would not be able to switch to any other mode anymore. Now the bits get cleared before the new flank will be written.

eed73beaa1 cpu/atmega_common: prepare for atmega328p inclusion
use generic avr/libc definition for conditionnal compilation.
eg: use #ifdef(PORTG) or #ifdef(TIMER_0_ISRC) instead of #ifdef(Atmega328p)
This is more generic and simplify future boards support.

2aec999900 cpu/atmega_common: generalize register/peripheral definitions
Makes AVR register definitions dependent on what avr-libc defines
for a given MCU, rather then duplicating that effort here.
Definitions done in this way are based on functionality provided,
rather than a specific MCU device.
