This provides an equivalent to `assert` and `assert_contextless` that
are always evaluated, ignoring `ODIN_DISABLE_ASSERT`, which is useful
for enforcing API contracts or "asserting" on conditionals with
side-effects.
`make(map[K]V)` was resolving to `make_map_cap()` which allocates initial capacity when it wasn't intended to.
It now calls `make_map()` which doesn't allocate any capacity.
Both `make(map[K]V)` and `make(map[K]V, allocator)` will NOT allocate initial capacity now.
Before this if you do `arr: [dynamic]int` and then append to arr, then it will have capacity 8.
But if you did `arr := make([dynamic]int, context.temp_allocator)` then arr would have capacity 16.
Now both `arr: [dynamic]int` and `arr := make([dynamic]int, context.temp_allocator)` will resut in arr having zero 0. The only reason to use `make` without an explicit len or cap now is because you want to set it up for a non-default allocator. After the first call to `append` it will now in both cases have capacity 8.
I also updated the documentation on the strings builder, both to reflect this, and also to fix it incorrectly saying that len would be 'max(16,len)', which wasn't true even before these changes.
