Update SPIRV-Tools to 1c336172 (#8739)

Fixes two SPIR-V validation failures under -O3:

- #8609: loop unrolling duplicated RelaxedPrecision decorations
  (KhronosGroup/SPIRV-Tools#6690)
- #8603: MergeBinaryOpSelect produced an OpSelect with a vector result
  type and a scalar condition, only legal in SPIR-V 1.4+
  (KhronosGroup/SPIRV-Tools#6827)

SPIRV-Headers moves to 29981f65 to match; SPIRV-Tools 1c336172 does not
build against the older headers.

XFAIL resource-heap-ext-texture: the validator now requires explicit
layout for UniformConstant when SPV_EXT_descriptor_heap is used
(KhronosGroup/SPIRV-Tools#6792).

[HLK] Remove preview-only GroupSharedLimit tests (#8703)

Removes the preview-only **GroupSharedLimit** HLK tests and their
supporting code from `release-1.9.2607`
The guards surrounding these tests will be insufficient to keep this
branch building for all future versions of the D3D12 SDK.
Given that these tests aren't even intended to be run for this release
its much simpler to just remove them in the release branch.

Update Release notes for 1.8.2505 (#7481)

This change updates release notes with notable changes for release
1.8.2505.

Update 1.8.2502 release notes (#7147)

An internal fix has changed the way PDB files are packaged on release.
This change is worth noting in the release notes for 1.8.2502.

Fix warning when use implicit launch type. (#6837) (#6841)

By default, the launch type should be set to ‘Broadcast’ when diagnosing
barriers. However, the current behavior sets the default launch type to
‘Invalid,’ resulting in warnings when the launch type is not explicitly
specified as an attribute.

To address this issue, we’ll adjust the default setting to ‘Broadcast’
and thereby resolve the problem.

Fixes #6836
