Subject: [PATCH] Windows: Use ATOMIC_PTR functions to avoid compiler warnings
due to incompatible types

HCRYPTPROV can be casted to pointer without warning but not to size_t.
Avoids the following warning/error:

../snapshot-master/random.c: In function 'fill_random_bytes_crypt':
../snapshot-master/include/ruby/atomic.h:246:28: warning: passing argument 1 of 'rbimpl_atomic_size_cas' from incompatible pointer type [-Wincompatible-pointer-types]
246 | rbimpl_atomic_size_cas(&(var), (oldval), (newval))
| ^~~~~~
| |
| HCRYPTPROV * {aka long unsigned int *}
../snapshot-master/ruby_atomic.h:16:46: note: in expansion of macro 'RUBY_ATOMIC_SIZE_CAS'
16 | #define ATOMIC_SIZE_CAS(var, oldval, newval) RUBY_ATOMIC_SIZE_CAS(var, oldval, newval)
| ^~~~~~~~~~~~~~~~~~~~
../snapshot-master/random.c:594:32: note: in expansion of macro 'ATOMIC_SIZE_CAS'
594 | old_prov = (HCRYPTPROV)ATOMIC_SIZE_CAS(perm_prov, 0, prov);
compiling ../snapshot-master/range.c
| ^~~~~~~~~~~~~~~
../snapshot-master/include/ruby/atomic.h:853:41: note: expected 'volatile size_t *' {aka 'volatile unsigned int *'} but argument is of type 'HCRYPTPROV *' {aka 'long unsigned int *'}
853 | rbimpl_atomic_size_cas(volatile size_t *ptr, size_t oldval, size_t newval)
| ~~~~~~~~~~~~~~~~~^~~
