We should check for that define during meson.build when gbm.found(),
to avoid potential later build errors.

This macro should be in EGL header for many years as this is a 2015 EGL
extension. Check the macro in meson.build is not necessary now like you
won't check all other EGL macros like EGL_DMA_BUF_PLANE0_OFFSET_EXT.

Imho we should still check for those macros, as they are extensions to egl.

Macros like EGL_DMA_BUF_PLANE0_OFFSET_EXT are also from EGL extension
but we don't check them. EGL_DMA_BUF_PLANE0_MODIFIER_LO_EXT makes
no difference. And we do need this macro to be always present to make
sure exporter
and importer of the texture to work correctly.
