dispatch: stop generating separate GLES1 API code.

This patch removes the generated files api_exec_es1.c,
api_exec_es1_dispatch.h, and api_exec_es1_remap_helper.h (and the
source files and build rules used to generate them), since they are no
longer used.  GLES1 now uses the same dispatch table layout as all the
other APIs.
