Matthäus G. Chajdas 723955cd2b FindVulkan: Fix for SDK versions < 1.0.42 on 32-bit Windows
Before Vulkan 1.0.42, the SDK would add the Bin directory to `PATH`,
which was confusing the 32-bit search on Windows.  Avoid such confusion
by ignoring the `PATH` when looking for the 32-bit version.

Vulkan 1.0.42 fixed the whole problem by moving the libraries into Lib,
Lib32, so this is strictly a compatibility fix for old SDKs.

# FindVulkan
# ----------
#
# Try to find Vulkan
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines :prop_tgt:`IMPORTED` target ``Vulkan::Vulkan``, if
# Vulkan has been found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables::
#
# Vulkan_FOUND - True if Vulkan was found
# Vulkan_INCLUDE_DIRS - include directories for Vulkan
# Vulkan_LIBRARIES - link against this library to use Vulkan
#
# The module will also define two cache variables::
#
# Vulkan_INCLUDE_DIR - the Vulkan include directory
# Vulkan_LIBRARY - the path to the Vulkan library
#
