  [SPIR] Set MaxAtomicInlineWidth minimum size to 32 for spir32 and 64 for spir64 (#148997)

Set MaxAtomicInlineWidth the same way as SPIR-V targets in 3cfd0c0d3697.
This PR fixes build warning in scoped atomic built-in in #146814:
`warning: large atomic operation may incur significant performance
penalty; ; the access size (2 bytes) exceeds the max lock-free size (0
bytes) [-Watomic-alignment]`
