LSC: Mark static const class/struct members as constexpr. This change fixes declarations that have initial values but are technically not definitions by marking them constexpr (which counts as a definition). This enables, among other things, the modified constants to be passed into functions and function templates that accept arguments by reference. Without this change, such functions would cause linker errors.
This change was approved as part of go/static-const-lsc.
Tested:
TAP --sample ran all affected tests and none failed
