vk_pipeline_cache: Fix unintentional memcpy into optional

The intention behind this was to assign a float to from an uint32_t, but
it was unintentionally being copied directly into the std::optional.

Copy to a temporary and assign that temporary to std::optional. This can
be replaced with std::bit_cast<float> once we are in C++20.
