Fix int16_t/uint16_t support for WGSL target (#7692)
* Initial plan
* Implement int16_t/uint16_t support for WGSL target
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Change int16_t/uint16_t to emit proper diagnostics instead of auto-promoting
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Implement diagnoseOnce to prevent duplicate diagnostics
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Optimize diagnoseOnce to use HashSet::add() return value
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Apply code formatting to slang-emit-c-like.h
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Fix diagnoseOnce to use all parameters instead of first parameter only
