Fix use-after-free in mrb_ary_delete()
...
`mrb_equal()` may call `obj.==` method internally.
Therefore, using an unupdated pointer and length after `mrb_equal()` could result in a read/write to an invalid address.
Fresh properties must always be obtained regardless of the result of `mrb_equal()`.
Also, `ary_modify()` must be called each time before writing.

array.c (mrb_ary_delete): protect return value; fix #6339
...
The C local variable is not protected from GC, so we use the function
mrb_gc_protect() to keep the value. We also keep the arena position by
mrb_gc_arena_save(), then restoring the position for every new return
value, to minimize arena size.
Small cosmetic changes (pre-increment to post-increment) are also made
in this commit.

array.c: no need to assert if blk is a Proc; ref #6344

Since `blk` always comes from `mrb_get_args`, it should always be either
`nil` or a Proc.

Need to restore the GC arena after some function calls
...
When calling `mrb_equal()` or `mrb_funcall()` family functions, the GC arena should be restored if the loop is repeated by a non-immediate return value.
In my opinion, restoring the GC arena is unnecessary when a non-immediate (true) value causes the function to return (e.g. the `mrb_ary_index_m()` function).
The patch does not take into account the case of recursive calls and may be incomplete.

Fix use-after-free for Array#<=>
...
The `mrb_ary_cmp()` function calls `mrb_cmp()` for comparison, but `mrb_cmp()` may call the `obj.<=>` method internally.
If a user-defined `<=>` method is called and the array object under comparison is expanded or reduced, a reference to an invalid address may subsequently be made.

array.c: replace sort! method implementation
...
- use heap sort (O(1)) instead of merge sort (O(n)) for better space
complexity.
- method implemented in C for better performance
As a result, simple sorting now consumes far less memory and is faster.
Since it's implemented in C, fiber context switching is not allowed from
comparison, but we consider the risk is minimal (no one switches context
in the comparison, right?)
