[Android] Add weex-rax-api.js for eagle

[YorkShen]

1. Add weex-rax-api.js for all eagle page
2. If it is eagle and Vue, set the value of weex-rax-api.js to \0
3. Change the json structure of weex.config.env.

• Before

  • Normal Page

    {
        "bundleType": "Vue",
        "bundleUrl": "xxxx",
        "env": {
            "deviceHeight": "1200",
            "deviceWidth": "720",
            "enableBackupThread": "true",
            "enableBackupThreadCache": "true",
            .....
        },
        "render_strategy": "DATA_RENDER"
    }
    

  • Eagle Page
    As bundleType is Others, env.options will not be merged into env.

    {
        "bundleType": "Others",
        "bundleUrl": "xxxx",
        "env": {
            "deviceHeight": "1200",
            "deviceWidth": "720",
            "options": {
                "enableBackupThread": "true",
                "enableBackupThreadCache": "true",
                .....
            }
            ....
        },
        "render_strategy": "DATA_RENDER"
    }
    

• After

  1. No matter what bundleType, always merge env.options into env

  2. For compatibility reason, remain the env.options at its original place.

        {
            "bundleType": "Other",
            "bundleUrl": "xxxx",
            "env": {
                "deviceHeight": "1200",
                "deviceWidth": "720",
                "enableBackupThread": "true",
                "enableBackupThreadCache": "true",
                "options": {
                    "enableBackupThread": "true",
                    "enableBackupThreadCache": "true",
                    .....
                }
                .....
            },
            "render_strategy": "DATA_RENDER"
        }
