Use textureLod instead of the texture

[jiaolu]

Description

texture() compiles to OpImageSampleImplicitLod, which needs screen-space derivatives of the UV if (rayQueryGetIntersectionTypeEXT(...) != ...NoneEXT) is per pixel ray query. one pixel ray query of the quad can hit while neighor misses.

So the divergent branch does not match the texture, should use textureLod which does not require the screen-space derivatives of quad pixels.

this PR Fixes ##1566

it replace texture with textureLoad, Hoisting the sample above the if isn't an option here

General Checklist:

Please ensure the following points are checked:

• My code follows the coding style
• I have reviewed file licenses
• I have commented any added functions (in line with Doxygen)
• I have commented any code that could be hard to understand
• My changes do not add any new compiler warnings
• My changes do not add any new validation layer errors or warnings
• I have used existing framework/helper functions where possible
• My changes do not add any regressions
• I have tested every sample to ensure everything runs correctly
• This PR describes the scope and expected impact of the changes I am making

Note: The Samples CI runs a number of checks including:

• I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)
• My changes build on Windows, Linux, macOS and Android. Otherwise I have documented any exceptions

If this PR contains framework changes:

• I did a full batch run using the batch command line argument to make sure all samples still work properly

Sample Checklist

If your PR contains a new or modified sample, these further checks must be carried out in addition to the General Checklist:

• I have tested the sample on at least one compliant Vulkan implementation
• If the sample is vendor-specific, I have tagged it appropriately
• I have stated on what implementation the sample has been tested so that others can test on different implementations and platforms
• Any dependent assets have been merged and published in downstream modules
• For new samples, I have added a paragraph with a summary to the appropriate chapter in the readme of the folder that the sample belongs to e.g. api samples readme
• For new samples, I have added a tutorial README.md file to guide users through what they need to know to implement code using this feature. For example, see conditional_rendering
• For new samples, I have added a link to the Antora navigation so that the sample will be listed at the Vulkan documentation site

Code changes look good, but there doesn't seem to be an updated SPIR-V file for the rayquery_morpheus.frag shader.

Right, the rayquery_morpheus.frag.spv is uploaded.

Thx. CI still fails, you need to adjust copyright in the text files you have updated.

@SaschaWillems I think there is something wrong with Clang Tidy in the CI environment. I am facing the same issue in a different PR (#1572).

[SaschaWillems]

Looks to be the case. I have no clue about that CI step, so can't really help. Maybe @gpx1000 knows.

re-commit to see if CI can run successfully this time.
