[C++] INTERVAL_MONTH_DAY_NANO passes the Primitive() type matcher but many kernels do not handle the 128-bit width

[felipecrv]

Describe the bug, including details regarding any error messages, version, and platform.

Example: the "filter" function, when applied to a interval_month_data_nano input selects the primitive kernel and hits the DCHECK(false) << "Invalid values bit width"; assert.

The specific case listed above was fixed in #39740 / #39795, but don't know it there are others
