config: add `lua.memory` option

Sometimes we need to limit Lua maximum available memory especially when
working in GC64 mode. Add the config property lua.memory to specify the
amount of memory used for Lua allocations.

The limit is implemented using a custom allocator supporting memory
limitation.

Closes #8881

@TarantoolBot document
Title: config: new `lua.memory` option.

Maximum amount of memory available for can now be specified using
a `lua.memory` config option.

The value represents amount of memory available to Lua in bytes. By
default it equals to 2GB. The limit can't be less than 256MB. Both
increasing and decreasing the limit is allowed if there would be enough
unused memory after applying a new value. Otherwise, the instance should
be restarted for the new limit to be applied.

Example for limiting Lua memory with 2GB:
```yaml
lua:
    memory: 2147483648
```
