[CI] Don't require SPIR-V Tools in Windows nightly

[sarnex]

Some people use the nightly and we don't want to require users to have it installed.

Manually verified the fix both by reproducing the original error and DependencyWalker.

Closes: #17950

Should the same go into the release builds?

[sarnex]

No idea
@KornevNikita, take?

Nope, the original patch didn't reach the sycl-rel-6-1-0 branch, so it doesn't require spirv-tools.

[sarnex]

ok so prolly patch is okay as is? @aelovikov-intel

[KornevNikita]

btw does the linux build work without spirv-tools?

[sarnex]

$ ldd bin/llvm-spirv
	linux-vdso.so.1 (0x00007fff31b02000)
	libz.so.1 => /lib64/libz.so.1 (0x00007fbd166e4000)
	libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fbd164bd000)
	libm.so.6 => /lib64/libm.so.6 (0x00007fbd163e2000)
	libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fbd163c7000)
	libc.so.6 => /lib64/libc.so.6 (0x00007fbd161bd000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fbd17b7a000)

Yeah seems fine
