fix(cli): restore Cordova Package.swift generator for Cap 9

[OS-pedrogustavobilro]

Description

Restores buildBinaryTargetEntries, buildResourcesText, buildDependencyTexts, buildCSettingsText, and the weak/required system-framework linker-settings logic in generateCordovaPackageFile()'s generated Package.swift branch.

Change Type

• Fix
• Feature
• Refactor
• Breaking Change
• Documentation
• Other (CI, chores, etc.)

Rationale / Problems Fixed

These methods were originally added by #8445, #8447, #8448, #8455, and #8457 on main, but then were collectively lost on a merge from main to next branch: next had already relocated this generator into cli/src/util/cordova-ios.ts (via #8328's Cordova-optional refactor), so main's still-monolithic update.ts was probably incorrectly treated as a stale deletion and none of the five PRs' new content was ported into Capacitor 9.

It's likely this has been like this for some time, and simply it missed us

I analysed other commits and merges (along with Claude 🤖), did not find any other kind of these issues

Tests or Reproductions

Test current Capacitor 9 alpha with a Cordova Plugin that requires updates to the auto-generated Package.swift file (I chose https://github.com/OutSystems/cordova-outsystems-healthfitness that contains an xcframework). You'll find that it fails to build on Xcode, but with this PR it builds.

Platforms Affected

• Android
• iOS
• Web

@OS-pedrogustavobilro I tested this myself first and it worked fine on my test. Then I asked Claude to verify and this is what it told me:

One real regression I found by running it, not just reading it: the original main code had a guard — skip writing Package.swift entirely if the plugin has no source files, header files, or resources (i.e., a JS-only Cordova plugin). That guard didn't make it into this restore. I proved it by running the function against a JS-only plugin fixture: it now writes an empty, sourceless Package.swift where main would write nothing.

I also checked whether this actually breaks builds today: cli/src/util/spm.ts (untouched by this PR) independently guards against wiring such plugins into the app's SPM dependency graph, so I don't believe this breaks swift build right now — it's a stray/dead file, not a build-breaker. Still worth a fix since it's a behavioral divergence from main and a latent trap for future code that assumes an empty target never exists.

Recommendation: minor fix needed before merge — restore the early-return guard in generateCordovaPackageFile's else branch. Everything else looks solid and the core fix is verified working.

Thanks for the review!

I believe that is referring to https://github.com/ionic-team/capacitor/pull/8443/changes - I've added it in this commit 24a0912
