cmds: Add evemu-record command

This is a Rust implementation of the command of the same name in the
FreeDesktop evemu suite [0].

The first version of this CL caused a build breakage on x86 due to
different sizes of the fields in libc::timeval. This version uses the
nix crate's wrapper to handle changes in timeval size by platform.

Bug: 302297266
Test: record events from an input peripheral (such as a mouse) and
      replay them using the FreeDesktop implementation of evemu-play
Ignore-AOSP-First: the directory does not yet exist in AOSP, so OWNERS
                   can safely be added here
