[RUM-18034] fix: tvOS build issue

[marco-saia-datadog]

What does this PR do?

Fixes the tvOS build (ref #1361) by guarding the remaining iOS-only DatadogWebViewTracking references: an import in DdSdkImplementation.swift and an unguarded consumeWebviewEvent bridge method in DdSdk.mm. Also adds a unit test that scans the native iOS sources for unguarded references to these symbols, to catch this kind of regression before it ships.

Additional Notes

Original PR by @MaeIg, thank you for your contribution!

Pull request overview

This PR fixes the tvOS build by ensuring iOS-only WebView tracking symbols and the consumeWebviewEvent React Native bridge entrypoint are not compiled on tvOS, and adds a unit test to prevent future unguarded references in iOS native sources.

Changes:

• Remove an unguarded DatadogWebViewTracking import from DdSdkImplementation.swift (keep iOS-only usage behind #if os(iOS)).
• Guard the consumeWebviewEvent React Native bridge method in DdSdk.mm with #if TARGET_OS_IOS.
• Add TvOSCompatibilityTests to statically scan ios/Sources for unguarded references to iOS-only symbols.

• XCTFail is being reported with file: #filePath (this test file) but line: UInt(lineNumber) from the scanned source file. This mismatch can make the failure location misleading (or point to a non-existent line in the test file). The message already includes the scanned file/line, so let XCTest report the failure at the call site.

                XCTFail(
                    "\(url.lastPathComponent):\(lineNumber) references iOS-only symbol " +
                        "'\(symbol)' without a '\(guardPattern)' guard. This will break the tvOS " +
                        "build: wrap this reference in the appropriate platform guard.",

• The #else handling in this guard scanner flips matches (matches: !top.matches). This makes any #else branch under an unrelated #if/#ifdef (e.g. #ifdef RCT_NEW_ARCH_ENABLED in Sources/DdSdk.mm) look "guarded" and therefore skip symbol checks, which can hide unguarded iOS-only references.

            if line.hasPrefix("#else") {
                if let top = stack.last {
                    stack[stack.count - 1] = (matches: !top.matches, parentGuarded: top.parentGuarded)
                }
