date: Improve nanosecond support

Add support for a field width, which defaults to 9 if unspecified or
zero. If the width is not exactly 9, we have to either cut off digits
or append zeroes to make up the difference. If the width is a dash,
we pick a width based on the clock's reported resolution. This brings
us in line with GNU coreutils.

date: Add support for nanoseconds

This patch introduces support for a conversion specification for
nanoseconds.

The format of %N is meant to be compatible with that of GNU date.

The nanoseconds conversion specification is implemented directly in
date(1) instead of libc (in strftime(3)) to avoid introducing
non-standard functions to libc at this time and modifying struct tm.

Apart from introducing the nanoseconds conversion specification, this
patch brings the following changes:

- The "ns" format for ISO 8061 dates is now unlocked. E.g., date -Ins
prints:
2024-04-22T12:20:28,763742224+02:00
- The -r flag when fed a file is now aware of the nanosecond part of the last
modification time.
- date(1) is now able to set the time with nanosecond precision. It is
not possible as of now to do that by specifying nanoseconds directly
via the command-line arguments. Instead, the -r flag can be used.
- date(1) is now using the clock_gettime(3) family of functions instead
of ctime(3) family of functions where possible.
