[clang-tidy] New Option Invalid Enum Default Initialization (#159220)

Added a new Option IgnoredEnums to bugprone invalid enum default
initialization to limit the scope of the analysis. This is needed to
remove warnings on enums like std::errc where the enum doesn't define a
value of 0, but is still used to check if some function calls like
std::from_chars are executed correctly.

The C++ Standard section 22.13.2 mentions the following : "[...] If the
member ec of the return value is such that the value is equal to the
value of a value-initialized errc, the conversion was successful [...]"

This means that a call to `std::errc{}` is clearly defined by the
standard and should not raise any warning under this check.
