Add LPUART1 definition for the STM32G4xx LPUART. It is possible to use LPUART1_BASE, but without the LPUART1 definition, usart_set_baudrate will calculate BRR incorrectly and the UART will not work due to an ifdef.
Tested and working @ 115200 on a NUCLEO-G474RE.
Other families used fdcanX_itY already, and that matches the terminology
of the reference manual, so move to that style for consistency.

The swapped lines generated the wrong nvic.h, then jumping into the wrong ISR.
See data sheet RM0440rev7 (page442, table 97).

Some class headers were not including stdint.h themselves, despite
relying on those types, and relying on them already being included
earlier elsewhere. Consistently include stdint.h where it's used.

Required so that the common uart infrastructure can be updated. This was
the last family to receive this implementation.

Follow HACKING specifications, be consistent with all other parts.
Yes, the SEL suffix is kinda superfluous, but it's _consistent_ which is
why we do it.

Cleanup one function at a time. Use the correct doxygen references, use
unshifted forms in user facing apis. Yes, only the trigger at the
moment, as the polarity is shared.

Add definitions for all the specific options, as is done for other
families.

(Added extra g0 definitions that were missed)
CCR register definitions were completely wrong, both decimal/hex mixups,
and straightup transcriptions from the reference manual errors.
Unify the styles for both g0 and g4, using the same (duplicated)
function for both implmentations.

Adds handling for missing cases. While i2c only has 3 cases, uarts have
all 4, so make sure they're handled properly.
Removes duplicated/redundant definitions.
Adds doxygen wrappers, even if only for internal use.
