buffer_create downconverts int64 size argument, preventing creating large buffers >2Gb

[thennothinghappened]

Description

As in the title, it doesn't seem possible to create buffers greater in size than the 32-bit signed integer limit.

Tested on Latest, and Beta Runtime v2023.1100.0.459.

Steps To Reproduce

Example code:

var i32 = 2_147_483_647;
show_debug_message(i32);

// ok
var b1 = buffer_create(i32, buffer_fixed, 1);
buffer_delete(b1);

var i64 = int64(2_147_483_648);
show_debug_message(i64);

// buffer_create: Illegal size -2147483648
var b2 = buffer_create(i64, buffer_fixed, 1);
buffer_delete(b2);

whoops, would've made more sense to check if GM was happy handling buffers that size first anyway :P

GM seems to completely fail loading anything above that size, it returns a totally empty buffer, but still says the buffer exists, so that's probably its own issue to report (or feature request for large buffer handling?)

Documented that buffers that are 2 Gibibytes or more cannot be created
