vulkan: repack 69-byte vertices to 72 bytes (#281)

Splatoon Raiders draws with a 69-byte vertex stride and a packed 4-byte
attribute at byte 65. Those fetches are unaligned, which Vulkan leaves
undefined: NVIDIA reads them as meant, the AMD Windows driver does not,
and the outdoor scenes turn into a white haze with horizontal streaks.

When a binding uses that layout, a compute pass copies it to a 72-byte
stride with the tail moved to byte 68, and the vertex input offsets and
stride follow. EGLANTINE_TEST_VERTEX_REPACK=0 turns it off;
EGLANTINE_EXPERIMENTAL_STATIC_VERTEX_REPACK=1 also covers pipelines
without dynamic vertex input.

Based on an outside patch (02-portable-vertex-repacking). Changes from
it: a range over the device limits skips the repack instead of throwing,
and the pipeline cache version stays, so caches are kept.
