wren_bind_xfer: use _Atomic keyword instead of stdatomic.h typedefs

MSVC's <stdatomic.h> doesn't typedef atomic_bool / atomic_uint to a
real atomic type, so the clang frontend (under /experimental:c11atomics)
errors with C7707 Ä atomic_load saw plain int instead of _Atomic int.

Switch to the keyword form (static _Atomic bool ...), matching the
pattern rlogin.c already uses for its rlogin_active / rlogin_input_paused flags.

Modified Files:
src/syncterm/wren_bind_xfer.c
Log Message:
wren_bind_xfer: undef __STDC_NO_ATOMICS__ before stdatomic.h on MSVC

MSVC defensively defines __STDC_NO_ATOMICS__, which makes
<stdatomic.h> expand to nothing Ä atomic_load/store/exchange fail
to compile. conn.h already uses this dance; mirror it here.

Also switch declarations to the _Atomic T form to match the
codebase convention (rlogin.c, threadwrap.h).

Modified Files:
src/syncterm/wren_bind_xfer.c
Log Message:
wren_bind_xfer: use plain access on _Atomic vars where it suffices

For _Atomic-qualified lvalues, plain reads and assignments emit
seq_cst atomic loads/stores Ä identical to atomic_load / atomic_store
with default memory order. The function forms only earn their keep
for atomic_exchange and atomic_compare_exchange_strong (no implicit equivalent), which stay.

Also sidesteps an MSVC clang-cl issue where atomic_load(&x) used
inline as a function argument expanded such that the address operator
got lost, leaving the underlying type where a pointer-to-atomic was
expected.
