[ANGLE]: fix is_always_lock_free assertion on 32 bit arch

https://bugs.webkit.org/show_bug.cgi?id=252670

Reviewed by NOBODY (OOPS!).

Remove is_always_lock_free assertion from AtomicQueueSerial

Build will fail when compiled on 32 bit architecture. The code will
still function on 32 bit architecture but with performance penalty due
to lock. But we are not really expecting it actually run on 32 bit
platform with vulkan backend (the atomic queue serial is only used by
vulkan backend). We could move AtomicQueueSerial into vulkan backend,
but that will be a much larger change that I try to avoid. This CL
removes the static_assertion and make it 8 bytes aligned as well.
