d5e4fc8356 remove __clang ifdef around atomic emulation
* CI errors led me to believe these were needed, but as it turns out the
load/store intrinsics are required even when idf is built by gcc when
linking to a clang based project.
* remove ... postfix inside `SYNC_LOCK_TEST_AND_SET` expansion

d93b53b9e5 newlib: provide missing atomic libcalls
Provide emulated atomic load & store libcalls for u8, u16 & u32 integer
types. This is required when building with Clang as llvm does not lower
these operations to native load / stores, where as gcc does.

Provide `sync_lock_test_and_set` atomic implementations for all
supported integer types.
