perf: Set isDirty to false to avoid JNI roundtrips

[mrousavy]

On iOS we had an optimization mechanism to set a flag called isDirty to false after a prop change has been applied to a Nitro View, causing the next prop update to only parse/set the props that have actually changed, and leave unchanged props untouched.
For views with a lot of props, this can save thousands of CPU cycles as these three steps:

• Parsing the jsi::Value to a C++ value
• The virtual method call to Swift
• Parsing the C++ value to a Swift value
  ...are all skipped.

On Android, this wasn't so simple - I had to create a react-native PR a few months ago, which luckily is now live in RN 79/80.
Now we can get a shared_ptr to the Props, allowing us to modify them (even if it looks unsafe), so this PR now brings this performance optimization to Android too - which should have an even greater impact since a JNI call is much more expensive than the virtual method call to swift.

So now this works on both platforms :)
