Enable some more clang-tidy linter checks (#4738)

* Avoid inefficient AString -> c_str() -> AString round trip

* Avoid redundant string init expressions

* Avoid unnecessary return, continue, etc.

* Add .clang-format to help with clang-tidy fix-its

* Avoid unnecessary passing by value

* Avoid unnecessary local copying

* Avoid copying in range-for loops

* Avoid over-complicated boolean expressions

* Some violations missed by my local clang-tidy

* Allow unnecessary continue statements

* Add brackets

* Another expression missed locally

* Move BindingsProcessor call into clang-tidy.sh and add space

* Fix pushd not found error

* Different grouping of CheckBlockInteractionRate
