Resist pins with WASD while unrestrained

[pgmzeta]

About the PR

Adds a check to resist pins with movement keys.

Why's this needed?

Better match other movement-restricted behavior: movement keys get you out of ice cubes and forces moves with other grabs.
Was suggested here: #9404 (comment)

Should apply to all grabs instead of just pins

[NightmareChamillian]

honestly I don't think it should apply to all grabs- pins are unique in that they're pretty easy to force someone into, especially if they're new, and insanely hard to escape from. Choking grabs are harder to pull off than pins and have a few things that can prevent them, and aggressive grabs are really easy to break out of, as well as not always being made with hostile intent.

The thing is 1. It seems unintuitive if wasd doesnt work for pins and works for grabs, and 2. Having wasd work doesnt make it easier to escape grabs because all it does is press resist for you on the same cooldown, it just makes it more intuitive and clear for new players to do. If making resisting grabs more intuitive makes grabs weaker due to more people actually knowing how to resist them that seems much more like a grab issue then a this change issue.
