BZLZHH a63699cde6 [Fix] (MG_Impl, MG_Backend): reject incomplete cube maps in mipmap generation instead of crashing on them
Both direct_state_access.textures_generate_mipmap* cases crashed DirectVulkan.
Two causes, neither of them a broken invariant:

glGenerateMipmap and glGenerateTextureMipmap never checked cube completeness, so
an incomplete cube map went straight to the backend, which asserts that the
texture it is handed is complete. GL 4.6 core 8.14.4 makes that call
INVALID_OPERATION - there is no consistent set of faces to filter down - and both
entry points now say so through a shared check.

VulkanRenderer::GenerateMipmap asserted that the target was one of the four it
implements. 1D, 1D array and cube map array are legal GL and the front end passes
them through, so meeting one is a gap in this backend's coverage; it now logs and
declines, leaving the generated levels unwritten rather than aborting.

textures_generate_mipmap_errors passes on both backends now. textures_generate_mipmaps
stops crashing but still fails: DirectVulkan does not generate the 1D mip chain
the case checks - the frontend's storage allocation gives the levels the right
sizes, which is why the case passes when run on its own, but not the descending
content the full-run state leaves it looking for.
