Picture just get "blown-up" when I use RoundingParams to get a rounded corner picture

### Description
I found an issue that seemed to be caused by RoundingParams, but was actually related to the mTargetDensity of the BitmapDrawable which used in RoundedBitmapDrawable

When the density changed by App-Self, the issue maybe appeared.
e.g. [AndroidAutoSize](https://github.com/JessYanCoding/AndroidAutoSize)

I want to getting this:

But got this:

### Reproduction


### Reason

The "blown-up" effect is the result of the updateTransform function：

Trace the following code：

https://github.com/facebook/fresco/blob/19c695fcc54237497fbc8a4a80c790f63668a0dd/drawee/src/main/java/com/facebook/drawee/drawable/RoundedBitmapDrawable.java#L45

Bitmap which used in RoundedBitmapDrawable was from this code：
https://github.com/facebook/fresco/blob/ba6965409a4d31d86c46771e610771dd37b0d51b/imagepipeline/src/main/java/com/facebook/imagepipeline/platform/DefaultDecoder.java#L276

The density of the bitmap which is created in DefaultDecoder is default, but when update transform in RoundedDrawable will use resource density which is changed by App-Self to measure transform

### Expected

Now, I solved it, by updating density of bitmap in some custom class, such as DrawableFactory or Postprocessor, but it's probably not safe, I hope to get a formal solution
