egl/dri2: Create EGLImages with dmabuf modifiers

Allow creating EGLImages with dmabuf format modifiers when target is
EGL_LINUX_DMA_BUF_EXT for EGL_EXT_image_dma_buf_import_modifiers.

v2:
- clear modifier assembling and error label name (Eric Engestrom)
v3:
- remove goto jumps within switch-case (Emil Velikov)
- treat zero as valid modifier (Daniel Stone)
- ensure same modifier across all dmabuf planes (Emil Velikov)
v4:
- allow modifiers to add extra planes (Louis-Francis Ratté-Boulianne)
v5:
- fix error checking, some cleanups (Jason Ekstrand)
- pass single copy of the modifier to createImageFromDmaBufs2
