Description
The validation of the allowed intrinsics for the "coalescing" launch mode is case-sensitive:
error: Invalid system value semantic 'SV_GroupThreadId' for launchtype 'Coalescing' const uint gtid : SV_GroupThreadId,

This is caused by this check here:

Hardcoding uppcase "SV_" for the thread lauch mode might also be unintentional.

Steps to Reproduce
Use e.g. SV_GroupThreadId instead of SV_GroupThreadID in the arguments of a [NodeLaunch("coalescing")] work graphs node.

Expected Behavior
Should compile with any capitalization combination of both the words "sv_groupthreadid" and "sv_groupindex".

Fix
toLower()...
