Add glMapBufferRange implemented via direct memory access
goldfish_address_space is a memory sharing device between
the QEMU host and an Android guest. This approach allows
to access host's memory from the guest directly without
copying bits.
Bug: 116046430
Test: Run the emulator with an OpenGL app that calls to
glMapBufferRange.
