## Description
Any platform function that accepts a callback were unable to access the
variables declared in its parent scopes. This was a implementation miss
when we originally designed platform functions and again when we turned
almost every platform function into a Promise. This PR fixes this
limitation along with some other edge cases.
- Access outer scope variables inside the callback of run, postMessage,
setInterval, getGeoLocation and watchGeolocation functions.
- Fixes certain edge cases where functions with callbacks when called
inside the then block doesn't get executed. Eg `showAlert.then(() => /*
Doesn't execute */ Api1.run(() => {}))`
- Changes the implementation of all the platform function in appsmith to
maintain the execution metadata (info on from where a function was
invoked, event associated with it etc)
#### Refactor changes
- Added a new folder **_fns_** that would now hold all the platform
functions.
- Introduced a new ExecutionMetadata singleton class that is now
responsible for hold all the meta data related to the current
evaluation.
- Remove TRIGGER_COLLECTOR array where all callback based platform
functions were batched and introduced an Event Emitter based
implementation to handle batched fn calls.
- All callback based functions now emits event when invoked. These
events have handlers attached to the TriggerEmitter object. These
handler does the job of batching these invocations and telling the main
thread. It also ensures that platform fn calls that gets triggered out
the the context of a request/response cycle work.
