Enable more OD pragmas

ProcArgumentGlobal, InvalidIndexOperation and AmbiguousInOrder

New Pragma: OD2211 - ProcArgumentGlobal from warning to error
A new pragma has been added for detecting this BYOND bug: https://www.byond.com/forum/post/2830750
When a proc argument begins with /var/ instead of var/, it creates a global variable instead of an argument.
/datum/proc/foo(/var/bar = 5)
return

/proc/main()
world.log << global.bar // This prints 5 in BYOND

Since this is obviously nonsense, elevating this pragma to an error is strongly encouraged. I have only found it in one SS13 codebase so far.

New Pragma: OD2304 - InvalidIndexOperation from warning to error
As of BYOND 515.1641, indexing datums (without an explicit operator[] overload) is now a runtime error in BYOND.

This new pragma detects such cases at compiletime, and elevating it to an error is strongly encouraged as previously-valid code that exists in SS13 will now runtime. It's a warning by default to maintain compatibility with older code & BYOND versions.

Example:
var/datum/foo = new
world.log << foo["bar"] // OD2304, Invalid index operation. datum[] index operations are not valid starting in BYOND 515.1641

New Pragma: OD3204 - AmbiguousInOrder from warning to error
A new pragma has been added for detecting ambiguous uses of in with unexpected behavior, similar to the lint in SpacemanDMM/DreamChecker. An example is "a" in a || "b" in b being parsed as ("a" in (a || "b")) in b. This is more comprehensive than SDMM's lint, and elevating this pragma to an error is strongly encouraged to detect logic errors.

needs #16883

or the task at least so i can run od locally easily
