Release 0.10.0: ergonomic API improvements and docs fixes

[Hiddentale]

Description

• Breaking: Private vk:: submodules, re-export types at crate root (vk::Buffer instead of vk::handles::Buffer)
• Breaking: Builder setters drop p_ prefix, cmd_push_constants takes &[u8], get_physical_device_surface_support_khr returns bool, optional const char* params take Option<&CStr>
• New builders for ~200 plain structs, all() on bitmasks, Display/Error on enums, typed ClearValue constructors, DeviceSize/DeviceAddress aliases, PartialOrd/Ord on bitmasks
• Typed PFN signatures, division-based array lengths, preserved count setters for optional pointers
• Fix docs.rs rendering with #[doc(inline)], fix crates.io broken links, correct guide version
