Make operator precedence explicit so the
`CPPTRACE_HAS_CXX_EXCEPTION_TYPE` define is a dominant switch to use
cxxabi.h, rather than one that only applies when `__GLIBCXX__` is
defined.
Fixes https://github.com/jeremy-rifkin/cpptrace/issues/121
This is (perhaps) mainly for discussion as I saw you removed
`clang-tidy` checks last year. These fix a variety of minor things.
With one of the options that I was using, these still remain:
```
/Users/bruce/Development/custodian/cpptrace/src/symbols/../utils/utils.hpp:235:22: warning: noexcept specifier on the move constructor evaluates to 'false' [performance-noexcept-move-constructor]
235 | noexcept(std::is_nothrow_move_constructible<T>::value)
| ^
/Users/bruce/Development/custodian/cpptrace/src/symbols/../utils/utils.hpp:250:64: warning: noexcept specifier on the move assignment operator evaluates to 'false' [performance-noexcept-move-constructor]
250 | noexcept(std::is_nothrow_move_assignable<T>::value && std::is_nothrow_move_constructible<T>::value)
| ^
```
This is set by the build system when it is available and not set when
not available (and not set to 1/0 respectively).
The current code can generate a warning when this preprocessor
definition is not defined.
