Template-fy recon_inter functions

Currently, the recon_inter functions are shared by both the encoder and
decoder, but the functions have different behaviors for encoder and
decoder. The "polymorphism" is accomplished by passing in a function
pointer to set up the parameters accordingly.

Since the parameter setup is relatively simple, significant time is
spent on going through the function call semantics for
CalcSubpelParamsFunc. This commit template-fy the recon_inter functions
so that we do not have to make a functional call to set up the subpel
params.

The performance improvement is slightly better on gcc compiler (~0.5%),
but lower on llvm.
