Document RWF_ATOMIC flag for pwritev2().

RWF_ATOMIC is used for enabling torn-write protection.

We use RWF_ATOMIC as this is legacy name for similar feature proposed in
the past.

Kernel support has now been merged into Linus' tree, to be released in
v6.11

Differences to v4:
- Add RB tags from Darrick (thanks)
- Revise description for readv.2 (Darrick)
- Re-order RWF_ATOMIC in readv.2

Differences to v3:
- Formatting changes (Alex)
 - semantic newlines
 - Add missing .TP in statx
 - Combine description of atomic write unit min and max
 - misc others
