libretro: scope Vulkan case to fix MSVC C2360 (#2267)

Browse Source 
MSVC with /permissive- /WX rejects the switch in retro_load_game:
the static vk_negotiation initializer in the Vulkan case is crossed
by the next case label (C2360, initialization skipped by case). Wrap
the Vulkan case body in a block so its scope ends before that label,
and add a comment noting why the braces are required there. The other
cases are wrapped in blocks too for visual consistency, though only
the Vulkan case strictly needs it. GCC/clang and the MXE cross-build
accept the original; this only affects native MSVC builds. No
behaviour change.
