Sample immediate offset range is not diagnosed or validated in SM 6.7

Description
In SM 6.6 and earlier, if you specify an immediate offset in a sample operation outside of the valid [-8,7] range, you get an error diagnostic for HLSL, or a validation error for DXIL. However, if you compile to SM 6.7 or later, no error diagnostic is emitted, DXIL will contain the out-of-range immediate offset, and no error is emitted from DxilValidation either.

Steps to Reproduce

Test for HLSL Diagnostic:

// RUN: %dxc -T ps_6_7 %s | FileCheck %s

// CHECK: error: Offsets to texture access operations must be between -8 and 7.

Texture2D T2D;
SamplerState S;

float4 main(float2 coord : TEXCOORD) : SV_Target {
  return T2D.Sample(S, coord, int2(12, -14));
}

Test for DxilValidation:

; RUN: %dxv %s | FileCheck %s

; CHECK: Function: main: error: offset texture instructions must take offset which can resolve to integer literal in the range -8 to 7.

Expected Behavior
Error diagnostic, or validation error for all shader models.

Actual Behavior
No diagnostic or validation error emitted when compiling to SM 6.7

Environment

• DXC version: 1.7 - 1.7.2308.7 (69e54e2); dxil.dll: 1.7(101.7.2308.12)
• Host Operating System: Operating System: Windows 10 22H2

Start with the HLSL and DXIL reproductions in the issue, using dxc with the ps_6_7 target and dxv on the supplied LLVM IR. Trace where immediate texture-sample offsets are diagnosed and validated for earlier shader models, then verify that out-of-range values produce an error for SM 6.7 and later as well.
