LOG: [CodeGenTypes] Remove redundant declarations (NFC) (#165972)

In C++17, static constexpr members are implicitly inline, so they no
longer require an out-of-line definition.

This patch also removes redundant "const" from the in-class definitions.

Identified with readability-redundant-declaration.
