Summary:
After reviewing the feasibility of adding new Runtime functionality, we
realized the current state of `Runtime` makes it hard/inconvenient to
add new basic functionality. It requires creating a new interface (e.g.
`IRuntime2`) to declare the new APIs. Then, everywhere it is needed,
both the original `Runtime` and `IRuntime2` needs to passed in to access
both APIs.

After discussion, we decided to introduce `IRuntime`, which will declare
most of the `Runtime` functionalities. All "protected" APIs, which made
sense before interfaces were introduced, will now be public. The
protected static methods of `Runtime` will remain as is for the Friends
to access.

After we decided to cut "stable" (after incoming JSI improvements), new
functionalities will be added in `IRuntime2` interface. `IRuntime2` will
inherit `IRuntime` to make existing functionality easy to access.

Summary:
Currently, the size of a jsi `Array` is immutable. Once the `Array` is
created, users can only set the element at an existing index, but not
append to it.

This change adds an `Array::push` API to improve ergonomics.

Differential Revision: D82254334
Summary:
Adds `ArrayBuffer::getMutableBuffer` to JSI. This allows the user to
retrieve a `MutableBuffer` from the `ArrayBuffer`. The data referenced
by the `MutableBuffer` will be alive during the entirety of the
`MutableBuffer` lifespan.

Summary:
Add TypedArray and Uint8Array types to JSI with supporting APIs.

New types:
- `TypedArray`: Base class for all typed arrays
- `Uint8Array`: Uint8Array type extending TypedArray

New IRuntime APIs:
- `buffer(TypedArray)`: Get underlying ArrayBuffer
- `byteOffset(TypedArray)`: Get byte offset property
- `byteLength(TypedArray)`: Get byte length property
- `length(TypedArray)`: Get length property
- `createUint8Array(size_t)`: Create Uint8Array with length
- `createUint8Array(ArrayBuffer, offset, length)`: Create from
  ArrayBuffer
- `isUint8Array(Object)`: Check if object is Uint8Array
