Enforce p_ prefixes for arguments in binds

[AThousandShips]

Improves general readability of generated code and prevents potential collisions

[AThousandShips]

My bad, missed this:

• Fix vararg methods forwarded to the ClassDB singleton #1485

Just making this an improvement

Thanks!

This makes sense to me: we use the p_ prefix in all the hand-written code, so let's do it for all the generated code too.

The changes here look good in a quick skimming! This just needs a rebase after having merged PR #1485

Some of the cases like Array has some non-prefixed cases, should I fix all the generated code with this? Like String etc. as well?

Edit: Since these are actually generated with these arguments in the source with this change I'll fix it all

I think we ultimately want to change all cases, so if there aren't any roadblocks to doing it now, let's do it!

Realized a few binds include r_ so will make those not include the p_, will push

Thanks! This looks great to me :-)
