spirv-tools: fix shared build

[valgur]

Summary

Changes to recipe: spirv-tools/[*]

Motivation

The spirv-tools recipe currently incorrectly builds several components as static when shared=True and skips packaging of them. This means that spirv-tools can only be used with shared=False when used together with glslang:

conan-center-index/recipes/glslang/all/conanfile.py

Lines 72 to 76 in a7603e7

	if self.options.enable_optimizer and self.dependencies["spirv-tools"].options.shared:
	raise ConanInvalidConfiguration(
	f"{self.ref} with enable_optimizer requires static spirv-tools, "
	"because SPIRV-Tools-opt is not built if shared"
	)

This limitation is only imposed by inconsistent naming of the CMake targets and Windows shared build issues: KhronosGroup/SPIRV-Tools#3909

Both of these can be worked around in the recipe while making the shared build actually usable on non-Windows systems.

Details

I have not tested the shared build on Windows yet.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
