Move emulator GLES from development.git to sdk.git

The emulator GLES support has two interfaces: a host shared library
interface used by QEMU, and a protocol between the platform and the
host. The host library interface is not versioned; QEMU and the GLES
renderer must match. The protocol on the other hand must be backwards
compatible: a new GLES renderer must support an older platform image.

Thus for branching purposes it makes more sense to put the GLES
renderer in sdk.git, which is branched along with qemu.git for SDK
releases. Platform images will be built against the protocol version
in the platform branch of sdk.git.
