Release notes for vulkan-loader:

build(deps): bump github/codeql-action from 3.26.5 to 3.26.6 
Document layer requirements for querying vkCreateInstance from GIPA 
  The vkGetInstanceProcAddr function was ammended in header version 1.2.193
  to require global functions be queried with NULL instance parameters,
  including vkCreateInstance. Layers written before that time may not expect
  the instance parameter to be NULL, so in order to maintain compatibility,
  the loader code (which itself dates to before Vulkan's public release) is
  left unmodified.
  Instead, code comments were left to indicate the non-spec compliant
  implementation as well as documentation in the LoaderLayerInterface mentioning
  how layers should handle the now invalid API usage.
  In the future, the loader could be modified to correctly follow the spec, but
  a survey of existing and previous layer implementations would need to be done
  to determine the impact of the change.
Remove unused VkIcdSurface struct members 
  All of the VkIcdSurface<API> members, as well as the *_size & offset members
  are unused by the codebase. And drivers do not have access to this struct, as
  it is internal to the loader - no common definition exists elsewhere for
  drivers to use either.
Stop reading json files twice 
  Split out the JSON file opening and reading logic into a Windows
  and Posix function to allow only reading the contents of a file
  once.
Only add include paths for xcb, x11, & directfb instead of linking 
  Previously, the loader linked to various windowing libraries but never
  made any calls into them. These can safely be removed, as including
  the libraries locations in the header search paths is sufficient.
  Because vulkan_core.h includes directfb.h without a path, it is
  necessary to add the search path found from pkg-config as well as
  the same path with `/directfb` appended to get vulkan_core.h to be
  able to find the header. This may be a bug in the vulkan_core.h
  or just an inconsistency with the way directfb is packaged on
  ubuntu 24, the system the change was developed on.
Add missing [[maybe_unused]] attributes in test_icd.cpp 
Fixup note for VK_DRIVER_FILES env-var 
  The original text was caused by a mistake during rebase which wasn't
  caught. This commit take the original non-mistake text and cleans that
  up further.
Add VK_IMPLICIT_LAYER_APTH & VK_ADD_IMPLICIT_LAYER_PATH env-vars 
  Add the environment variables VK_IMPLICIT_LAYER_PATH and
  VK_ADD_IMPLICIT_LAYER_PATH to control implicit layer path searching,
  mirroring the existing explicit layer only VK_LAYER_PATH and
  VK_ADD_LAYER_PATH.
  This fixes a gap in environment variable controls over the behavior
  of the loader.
Documentation fixes 
Small cleanup of regression tests 
build(deps): bump github/codeql-action from 3.26.6 to 3.26.7 
Define _FILE_OFFSET_BITS=64 for 32 bit linux builds 
  Certain file systems (such as bcachefs) use 64 bit inodes, which glibc truncates
  to 32 bits by default. This causes EOVERFLOW to be returned from readdir, causing
  not all files to be read from a directory.
  The fix is to use the 64 bit versions of file system access functions, by defining
  _FILE_OFFSET_BITS=64 in 32 bit builds.
  Because this issue does not affect 64 bit builds, it is only applied to 32 bit
  builds.
  The test framework required explicitly referencing readdir64, the Large File
  Support version of readdir found in glibc due to the function interposition that
  the test framework does.
  Additionally, readdir now will check errno after being called and report the
  error code if it is non-zero, reporting any other issues encountered to the user
  through the error stream. This doesn't apply to Windows due to implementing
  readdir ontop of _findnext, which behaves differently.
Fix Windows build warning about mismatching library and def file names 
build(deps): bump github/codeql-action from 3.26.7 to 3.26.8 
Only initialize mutexes during DllMain 
  Defer all other loader initialization on Windows to after the call
  to DllMain by using InitOnceExecuteOnce, mirroring the initialization
  needed for statically linked MacOS.
  This commit makes the loader follow Dynamic-Link Library Best Practices
  as defined by Microsoft from the following article:
  https://learn.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-best-practices
Fix windows_read_sorted_physical_devices buffer overrun 
Add tests fo windows read sorted adapters buffer overrun 
  Exercises the situation where there are enough adapters per physical
  gpu to cause resizing of the buffer which stores them.
