MVKImage: Handle VK_IMAGE_CREATE_EXTENDED_USAGE_BIT.

If this bit is set, add `MTLTextureUsage` bits for features supported by
all possible view formats, not just the image format. Happily, Metal's
API validator layer is OK with this.

This is needed for the mutable format tests, which use this bit with a
format that doesn't support writing, then casts the image to a format
which does.
