BUG: Mitosis does not camelCase HTML attributes in React

**Scope**
- [ ] This impacts ALL Mitosis outputs
- [x] This only impacts specific generators/outputs (please list them here): React

**Describe the bug**
Attributes like `srcset` are camelCased in React (possibly other frameworks? Not sure). However, Mitosis does not account for that

**To Reproduce**

A link to a https://mitosis.builder.io/ fiddle containing the bug: [link](https://mitosis.builder.io/?outputTab=react&code=import+%7B+useState+%7D+from+%22%40builder.io%2Fmitosis%22%3B%0A%0Aexport+default+function+MyComponent%28props%29+%7B%0A++const+%5Bname%2C+setName%5D+%3D+useState%28%22Steve%22%29%3B%0A%0A++return+%28%0A++++%3Cdiv%3E%0A++++++%3Cimg+srcset%3D%22http%3A%2F%2Fexample.com%22+%2F%3E++++%3C%2Fdiv%3E%0A++%29%3B%0A%7D)

**Expected behavior**
`scrset` should become `srcSet` in the React output. Same goes for all HTML attributes that are multi-word: https://reactjs.org/docs/dom-elements.html

**Additional context**
- I am not sure what the comprehensive list of camelCased DOM elements is, but we can probably look at React's JSX types to determine what to do
- I am also not sure if other frameworks do this camelCasing. We might need to do this elsewhere too
