Add realtime scheduling calls to std.os.linux (issue #19671)

[Uthedris]

Add the following system calls to std.os.linux:

• sched_setscheduler
• sched_getscheduler
• sched_setparam
• sched_getparam
• sched_get_priority_min
• sched_get_priority_max

Also add required sched_param structure and SCHED constant definitions:

• pub const sched_param
• pub const SCHED

Looks good with a few minor adjustments.

If you feel like it, it would be nice to also have these:

• sched_getcpu
• sched_getattr/sched_setattr
• sched_rr_get_interval

But that's not required to merge this, so if you don't feel like it, that's totally fine. :slightly_smiling_face:

@curuvar do you think you'll be able to address my review comments soon? If you don't have time, that's totally fine; I can make the adjustments in that case.

[Uthedris]

I’ll make the changes.

I made the requested changes and added:

sched_getcpu sched_getattr sched_setattr sched_rr_get_interval

and "getcpu" as it was needed for sched_getcpu.

Nice, thanks! Just a couple of naming nitpicks and I think this one is good to go.
