fix: repairs $EXTRA_COMPILER_ARGS error with multiple args

[fergusean]

Summary:

Fixes a regression added on merge of #37531 (though oddly I don't see it in #37531's diff, so perhaps added during conflict resolution?) where multiple arguments in $EXTRA_COMPILER_ARGS are now incorrectly wrapped in quotes, including RN's own sourcemap support:

runner@SeansMacBookGo sampleapp % /Users/runner/builds/y_x6gsp4/0/sampleapp/ios/Pods/hermes-engine/destroot/bin/hermesc -emit-binary -max-diagnostic-width=80 '-O -output-source-map' -out /Users/runner/builds/y_x6gsp4/0/sampleapp/ios/build/derived-data/Build/Intermediates.noindex/ArchiveIntermediates/sampleapp/BuildProductsPath/Release-iphoneos/sampleapp.app/main.jsbundle /Users/runner/builds/y_x6gsp4/0/sampleapp/ios/build/derived-data/Build/Intermediates.noindex/ArchiveIntermediates/sampleapp/BuildProductsPath/Release-iphoneos/main.jsbundle
hermesc: Unknown command line argument '-O -output-source-map'.  Try: '/Users/runner/builds/y_x6gsp4/0/sampleapp/ios/Pods/hermes-engine/destroot/bin/hermesc -help'
hermesc: Did you mean '-output-source-map'?

Changelog:

[IOS] [FIXED] - Fix build error when there are multiple EXTRA_COMPILER_ARGS

Test Plan:

Removing the quotes and running the command results a successful run of hermesc (exit code 0 and the expected files produced).

I have noticed the same issue as well, I cannot generate sourcemaps on iOS with RN 0.72.

I've applied the changes described here with the following test plan to further test this fix and can attest that it works:

1. Create a new RN project using npx react-native@latest init SourcemapsDemoApp
2. Add export SOURCEMAP_FILE=./main.jsbundle.map to the end of the ios/.xcode.env file
3. Open the project on XCode with xed ios
4. Change the XCode Scheme to set "Release" as build configuration
5. Build the project
6. The build fails
7. Edit node_modules/react-native/scripts/react-native-xcode.sh with the content from this PR
8. The build succeeds
9. Remove the line from ios/.xcode.env and rebuild
10. The build succeeds again

Thanks for noticing. It was a mistake on my side. I'm going to have this landed.
