I'll leave this PR open because ruby/rbs only runs CI on pull requests, so we need this PR to have CI constantly running against changes in c-api.

vasprintf is not available on all platforms (e.g. Windows). So we should
switch to vsnprintf even tho it'd complicate the code a bit.
This commit addresses several compatibility issues with MSVC compiler:

1. Updated NODISCARD macro in defines.h to use MSVC-specific _Check_return_ attribute
   instead of GCC/Clang's __attribute__((warn_unused_result)).

2. Fixed variable-length array (VLA) parameter in rbs_parser_declare_type_variables
   function. Changed from `const char *variables[count]` to `const char **variables`
   since VLAs are not supported in MSVC.

3. Added the declaration of rbs_parser_declare_type_variables to parserstate.h
   to ensure proper function prototyping.

4. Rename `error` label to `error_handling` to avoid syntax error on mswin.

These changes maintain the same functionality while ensuring compatibility
with MSVC, allowing the RBS extension to build successfully on Windows.
This code was added for easier debugging but it's not needed anymore
and would fail memory leak checks.
Rename alloc_location to rbs_location_new

Use rbs_location_current_token when possible
* Make rbs_loca_add* methods take allocator

* Remove unnecessary rbs_new_loc_range helper function

* Make rbs_loc_alloc_children allocate through allocator

* Rename check_children_cap to ensure_children_capacity

* Implement rbs_allocator_realloc function

* Reorganize location children functions

* Update src/rbs_location.c

* Remove unnecessary re-allocations from child-adding functions

We always pre-allocate enough space for a location's children with
`rbs_loc_alloc_children` in `parser.c`. So we should never hit the
case where we need to re-allocate the children array.

This change removes the unnecessary re-allocations and makes the code
simpler.

* Update src/rbs_location.c

* Allocate parser error with allocator

* Allocate parse result with allocator
Since we don't manually allocate/free strings anymore, we don't need the string type enum
and all the complexity that comes with it.
* Remove unnecessary rbs_buffer_init_with_capacity function

* Manage buffer allocation with allocator

* Set default capacity for buffer to 128

Most comments are less than 128 bytes, so this should help reduce memory waste.

See #13 (comment)
Add `rbs_allocator_alloc_many` to avoid unnecessary 0 initialization on memory
### Avoid declaring unused `node` variables in `rbs_node_destroy`'s template

Such declarations will fail Sorbet's compiler:

```
prism/templates/src/ast.c.erb:203:31: error: unused variable 'node' [-Werror,-Wunused-variable]
        rbs_ast_annotation_t *node = (rbs_ast_annotation_t *)any_node;
                              ^
prism/templates/src/ast.c.erb:203:28: error: unused variable 'node' [-Werror,-Wunused-variable]
        rbs_ast_comment_t *node = (rbs_ast_comment_t *)any_node;
                           ^
prism/templates/src/ast.c.erb:203:28: error: unused variable 'node' [-Werror,-Wunused-variable]
        rbs_ast_integer_t *node = (rbs_ast_integer_t *)any_node;
                           ^
prism/templates/src/ast.c.erb:203:27: error: unused variable 'node' [-Werror,-Wunused-variable]
        rbs_ast_string_t *node = (rbs_ast_string_t *)any_node;
                          ^
```

### Use `size_t` instead of `int` for `capacity` in `rbs_loc_alloc_children`

This fixes a warning about comparing `int` and `size_t` in `rbs_loc_alloc_children`'s assertion.

### Avoid declaring the `max` variable that's just used in assertions

When the `assert` is stripped out, the variable becomes unused and triggers a warning.

```
external/rbs_parser/src/rbs_location.c:8:10: warning: unused variable 'max' [-Wunused-variable]
  size_t max = sizeof(rbs_loc_entry_bitmap) * 8;
         ^
```
