mesa: refactor _mesa_compute_max_transform_feedback_vertices from i965.
Previously, the i965 driver contained code to compute the maximum
number of vertices that could be written without overflowing any
transform feedback buffers. This code wasn't driver-specific, and for
GLES3 support we're going to need to use it in core mesa. So this
patch moves the code into a core mesa function,
_mesa_compute_max_transform_feedback_vertices().

v2: Eliminate C++-style variable declarations, since these won't work
with MSVC.
