refactor: Enable more clang-tidy readability checks

[godexsoft]

High Level Overview of Change

This PR enables the following checks:

• readability-convert-member-functions-to-static
• readability-implicit-bool-conversion
• readability-math-missing-parentheses
• readability-simplify-boolean-expr
• readability-suspicious-call-argument

For some of them NOLINTs have been added (for things like to_string or some functions that should not be static but clang-tidy insists).
The other two checks that are left (other than the huge identifier-naming one - #6571) I think we want to leave out:

• readability-inconsistent-declaration-parameter-name - in this codebase this check will break a lot of arg names because clang-tidy will take names from .cpp file and match them in .h files. this breaks doxygen where present as well as most names in .cpp files are much worse than the ones currently in headers.
• readability-static-accessed-through-instance - this check is probably unnecessary. it makes the code less readable for many types like types based on base_uint for example.

Context of Change

API Impact

No impact.

• Public API: New feature (new methods and/or new fields)
• Public API: Breaking change (in general, breaking changes should only impact the next api_version)
• libxrpl change (any change that may affect libxrpl or dependents of libxrpl)
• Peer protocol change (must be backward compatible or bump the peer protocol version)
