feat(feedback): Support web environments (#4558)

* Save form state for unsubmitted data

* Show selected screenshot

* Use image uri instead of UInt8Array in  onAddScreenshot callback

* Omit isVisible from state

* Save/clear form state on unmount

* Pass the missing attachment parameter in the onSubmitSuccess

* Use only the uri parameter for the onAddScreenshot callback

* Handle attachments on the web

* Use window for showing alerts on the web

* Disable keyboard handling on the web

* Use instance variable for _didSubmitForm

* Fixed callback function parameter name for clarity

* Fixes lint issue

* Use RN_GLOBAL_OBJ for web alert
