Allow override configuration of any_bad_access, optional_bad_access, variant_bad_access, monostate

[martinmoene]

Allow override via macros like any_CONFIG_OVERRRIDE_BAD_ANY_CAST.

See variant-lite PR 55.

Plan:

• any-lite, bad_any_cast.
• optional-lite, bad_optional_access.
• variant-lite, bad_variant_access, monostate.
