[clang-tidy] Disable Checks on If constexpr statements in template Instantiations for BugproneBranchClone and ReadabilityBracesAroundStatements

Summary: fixes readability-braces-around-statements broken for if constexpr and bugprone-branch-clone false positive with template functions and constexpr by disabling the relevant checks on if constexpr statements while inside an instantiated template. This is due to how the else branch of an if constexpr statement is folded away to a null statement if the condition evaluates to false
