[clang-tidy] Extension of checker misc-misplaced-widening-cast

[clang-tidy] Extension of checker misc-misplaced-widening-cast

Summary:
Existing checker misc-misplaced-widening-cast was extended:
- New use cases: casted expression as lhs or rhs of a logical comparison or function argument
- New types: beside int, long and long long various char types, short and int128 added
- New option to check implicit casts: forgetting a cast is at least as common and as dangerous as misplacing it. This option can be disabled.

This patch depends on AST Matcher patches D17986 and D18243 and also contains fix for checker misc-bool-pointer-implicit-conversion needed because of the fix in the AST Matcher patch.
