Greg Fischer 90c5214344 Improve ResourceLimits interface to be more forward compatible
New interface allows users to generate ResourceLimits for interface so
that additions to TBuiltInResource do not break the ABI.

Users should use the glslang-default-resource-limits library and the
Public/ResourceLimits.h header. Similar changes have been made to the
C interface. Use Public/resource_limits_c.h.

Fixes #2822
