No way to remove struct names from shaders

[GlassBeaver]

Description
Struct names are left in shaders even when using -Qstrip_debug -Qstrip_priv -Qstrip_reflect
IDxcContainerBuilder::RemovePart also fails to remove them.

Steps to Reproduce
Compile any shader that's using a structured buffer with a named struct e.g. struct CSomething { ... } using the following command line arguments:

"-T"
"ps_6_6"
"-Zpr"
"-Qstrip_debug"
"-Qstrip_priv"
"-Qstrip_reflect"
"-E"
"BlackholePS"
"-Ges"
"-Wshadow"
"-WX"
"-Fo"
"out.cso"
"test.hlsl"

Make sure to run IDxcContainerBuilder::RemovePart with all the removable fourcc codes ("ILDB", "ILDN", "PRIV", etc.)

Actual Behavior
PIX is still able to detect struct names in the stripped DXIL, e.g.:
%ResourceIndexRootConstants = type { %struct.CResourceIndexRootConstants }

Environment

• DXC version 1.8.2505.28
• Host Operating System Windows 11 x64 24H2 26100.4349

While this isn't something we'll be scheduling time to work on, we'd gladly consider any PR's that strip these names out.

@damyanp Hi, sorry for the ping but I've implemented PR #7868 to fix this. A review had started on it but got stalled and now I'm not sure if it's going to get picked up again any time soon. Wondering if you could maybe take a look or assign it to someone. I understand that it's not the most important PR in the world but since you've said you'd consider a PR I thought I'd ask.
