meson: bump spirv-tools version needed to v2022.1

Since c60a421f0c ("vtn: Add a debug flag to dump SPIR-V
assembly"), we use SPIR-V 1.6, which was added in `spirv-tools 2022.1`.

Fixes: c60a421f0c ("vtn: Add a debug flag to dump SPIR-V assembly")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11802
(cherry picked from commit 95c2496412)
