feat: add path property to custom event

[YoloMao]

PR 内容

• GrowingCustomEvent 添加 path 字段，通过 customEventWithPath 配置项设置是否携带最后一个 PAGE 事件的 path
• 移除不必要的 GrowingHybridCustomEvent

Important

注意测试 JSON/Protobuf/SwiftProtobuf 三种环境下，CustomEvent 是否正常携带 path 字段

SwiftPM 测试步骤（20240929）

集成步骤

1. 使用以下内容替换 Podfile 所有内容：

platform :ios, '12.0'
use_frameworks!

install!'cocoapods',:deterministic_uuids=>false, :warn_for_unused_master_specs_repo=>false

workspace 'GrowingAnalytics.xcworkspace'
project 'Example'

target 'Example' do
  pod 'SDCycleScrollView', '~> 1.75'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
    end
    if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle"
      target.build_configurations.each do |config|
          config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
      end
    end
  end
end

2. 执行 pod install，这将移除 demo 使用 cocoapods 集成的 GrowingAnalytics SDK
3. 打开 GrowingAnalytics.xcworkspace，按下图步骤打开 Swift Packages 添加页面
   
4. 点击 Add Local... 添加本地 Package，选择已 clone 至本地的 growing-sdk-ios-autotracker 文件夹(比如当前分支，可通过指令：git clone https://github.com/growingio/growingio-sdk-ios-autotracker.git -b feat/cstm_path --depth=1)，Add to project 选择 Example，之后点击 Add Package
5. 同样的步骤，添加 growingio-sdk-ios-toolskit 文件夹 (可选)
6. 找到 TARGETS -> Example -> Frameworks, Libraries, and Embedded Content，点击加号，添加 GrowingAutotracker
7. 同样的步骤，添加 GrowingToolsKit (可选，需要在 Other Linker Flags 添加 -ObjC)
   
8. 找到 TARGETS -> ShareExtension -> Frameworks, Libraries, and Embedded Content，点击加号，添加 GrowingAutotracker
9. 找到 TARGETS -> Example-watchOS Watch App -> Frameworks, Libraries, and Embedded Content，点击加号，添加 GrowingTracker
10. 运行 Demo，测试在 SwiftPM 集成下，事件数据所有字段是否能够正常地在远端服务器落库
