Add Bazel 8 compatibility support

This commit adds full support for Bazel 8 while maintaining backward
compatibility with Bazel 7.

Changes:
- Fix ObjcInfo provider compatibility: Add hasattr checks for fields
removed in Bazel 8 (force_load_library, imported_library, library,
static_framework_file, etc.)
- Handle AppleDynamicFramework provider removal: Add conditional checks
and fallbacks for the removed provider
- Update MODULE.bazel dependencies to Bazel 8-compatible versions:
  - apple_support: 1.15.1 → 1.21.1
  - rules_cc: 0.0.10 → 0.0.16
  - bazel_skylib: 1.4.2 → 1.7.1
  - rules_pkg: 0.9.1 → 1.0.1
  - stardoc: 0.6.2 → 0.7.2
- Add bazel_version.bzl utility for runtime version detection
- Update CI to test with both Bazel 7.1.0 and 8.0.0
- Add Bazel 8 migration guide to README
- Add compatibility test script

Fixes compatibility issues when using rules_ios with Bazel 8.0.0

+## Bazel 8 Migration Guide
+
+If you're upgrading from Bazel 7 to Bazel 8, please note the following changes:
+
+### Important Changes
+- The `apple_common.AppleDynamicFramework` provider has been removed in Bazel 8
+- Several ObjcInfo provider fields have been removed, including:
+  - `force_load_library`
+  - `imported_library`
+  - `library`
+  - `static_framework_file`
+  - And others related to linking
+
+### Required Updates
+1. Update rules_ios to version 5.4.0 or later
+2. Update your dependencies in MODULE.bazel:
+   - `apple_support` to 1.21.1 or later
+   - `rules_cc` to 0.0.16 or later
+   - `bazel_skylib` to 1.7.1 or later
+
+### Compatibility
+rules_ios 5.4.0+ maintains compatibility with both Bazel 7 and Bazel 8, so you can safely update before migrating to Bazel 8.
