Remove core modules from the default tmmdelegate (#43939)

Summary:
Pull Request resolved: #43939

## Problem
If we link the default tmmdelegate with our vr apps, we get this issue:

```
ld.lld: error: duplicate symbol: facebook::react::NativeDevLoadingViewSpecJSI::NativeDevLoadingViewSpecJSI(facebook::react::JavaTurboModule::InitParams const&)

```

## Cause
My best understanding of the problem:
- Default tmmdelegate links against rncore, which contains codegen for react native's standard library of modules.
- But, the default delegate also pulls in this appmodules.so library. That library also contains codegen for react native's standard library of modules + the app's modules.

So, two so libraries define the same symbols. Hence the build fails.

## Solution
Remove the codegen for react native's standard library of modules from the default tmmdelegate.

Prereq: In open source, also make appmodules.so include the codegen for react native's standard library of modules.
