Improve method table performance by rehashing at 75% load factor.
...
The method table (mt_tbl) in src/class.c previously only rehashed when it became completely full. With linear probing, this could lead to significant performance degradation for lookups and insertions as the table approached full capacity.
This change introduces a load factor (MT_LOAD_FACTOR_NUM/MT_LOAD_FACTOR_DEN, set to 3/4 or 0.75). The mt_put function now checks if adding a new element would cause the table's size to meet or exceed this load factor relative to its allocated capacity. If so, it triggers a rehash before inserting the new element.
This helps maintain more empty slots in the hash table, improving the average-case performance of linear probing and reducing the likelihood of worst-case scenarios. The existing initial allocation size and doubling strategy for rehashing are retained.

class.c (mt_rehash): Fix mrb_calloc argument order
...
Since mrb_calloc() (along with mrb_calloc) takes two arguments: nmemb
which is number of array elements, and size which is size of the array.
Of course, revsersing does not change the behavior, but we'd like to
respect the original design intention of calloc(3).

Since the function returns either callinfo or env, thus the name does

on the function.

class.c (append_features): remove the method
...
The technique is called "double dispatch" (that was popular in
Smalltalk), but it does not work well with mruby. It's slower and
consumes more memory. Even thought `#append_features` defined in ISO
standard (15.2.2.4.11), we decided to remove it. Strictly speaking, it
is mruby limitation. And it should be documented clearly.

Fixed visibility at method definition
...
There was a problem with visibility state from proc that straddles a fiber or is independent.
Therefore, it has been changed to give priority to env objects, if any.
Also, added "separate module" flag to block traversal to a higher level env object.
Note that the "separate module" flag is now set when calling blocks with the `mrb_yield_with_class()` function.
