blade: Update blade to b37a9a9 to fix leaking memory (#16935)

Bumps blade to `b37a9a994709d256f4634efd29281c78ba89071a` which
importantly includes a fix for leaking memory from Vulkan objects when
creating and destroying the context.

This improves https://github.com/zed-industries/zed/issues/13346, but I
think there are still some improvements to be made.
