cmake: Use NOMINMAX on Windows

[RytoEX]

Description

This PR makes a few changes.

1. Explicitly use std::min
2. Explicitly use std::max
3. Set NOMINMAX as a default compile definition on Windows to prevent defining min/max macros

Motivation and Context

Want to just use STL std::min/std::max and avoid shenanigans with min/max macros.

How Has This Been Tested?

Built locally on Windows 11. Still needs built with VS for/on WoA to make sure it works.

Types of changes

• Code cleanup (non-breaking change which makes code smaller or more readable)

There's still two more instances of specific NOMINMAX use:

Removed those. Thanks.

The commits may need squashed to avoid the first two commits failing.
