Fix SLANGC_EXECUTABLE search path in slangConfig.cmake (#8200)

This patch changes the order of searching slangc executable. This bug
affects the following scenario: let's assume that user has a binary
release of slang package and wants to use it via `find_package(slang
CONFIG HINTS <path to binary release>)`, but there is also an
environment variable that points to some other slang release (e.g. user
has Vulkan SDK in the `$PATH`). In that case, find_package will
successfully find a desired slang package, but find_program in
slangConfig.cmake will check environment variable first, and in the
result SLANGC_EXECUTABLE will point to slangc from Vulkan SDK and not
from the downloaded package.
