Fix debug info generation for let variables in SPIR-V output (#7743)
* Initial plan
* Fix debug info for let variables
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Fix parameter count for emitDebugVar function call
Fixed regression where let variable debug info generation was missing the optional argIndex parameter in emitDebugVar call.

* Add location validity check for debug info generation
Co-authored-by: csyonghe <2652293+csyonghe@users.noreply.github.com>
* Don't insert debug value for nondebuggable types.
