Out-of-line construction of OperatorName. (#32121)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/32121
This reduces code size in the call sites of this function (of which
there are many: one for every operator call) since we no longer have
to construct std::string at the site.
