Summary:
We intended to enable Fusebox on main since #45469 — this worked when building under Buck, however was not working for builds under Xcode/Android Studio. This is because the HERMES_ENABLE_DEBUGGER preprocessor flag is not equivalently defined in these build configurations.

This diff genericises these checks to !defined(NDEBUG) (i.e. any debug build), meaning we are correctly able to evaluate the ReactNativeFeatureFlags::fuseboxEnabledDebug() setting.

Changelog: [Internal]

NOTE: NDEBUG should be the as-generic-as-possible choice to select a debug build in both OSS and fbsource. Having HERMES_ENABLE_DEBUGGER set remains significant (AFAIK) within the Hermes codebase (there are no other references in jsinspector-modern). Evaluation of whether the lack of this flag works in OSS continues in T200241280.

Pull Request resolved: facebook#46282

We intended to enable Fusebox on `main` since facebook#45469 — this worked when building under Buck, however was not working for builds under Xcode/Android Studio. This is because the `HERMES_ENABLE_DEBUGGER` preprocessor flag is not equivalently defined in these build configurations.

This diff genericises these checks to `!defined(NDEBUG)` (i.e. *any debug build*), meaning we are correctly able to evaluate the `ReactNativeFeatureFlags::fuseboxEnabledDebug()` setting.

Changelog: [Internal]

NOTE: `NDEBUG` should be the as-generic-as-possible choice to select a debug build in both OSS and fbsource. Having `HERMES_ENABLE_DEBUGGER` set remains significant (AFAIK) **within the Hermes codebase** (there are no other references in `jsinspector-modern`). Evaluation of whether the lack of this flag works in OSS continues in T200241280.
