feat: introduce $close method and bind option

[sheremet-va]

Description

This PR addresses two issues I have with the current implementation:

• The context is lost when I pass down an instance of a class (I don't actually want methods inside to reference each other as rpc calls): https://github.com/vitest-dev/vscode/blob/61b37b9ca6b0415d1c511c3e836bd5f92ba2df67/src/worker/worker.ts#L35
• There is no native way to stop the promise if the connection has been lost/disconnected, which leads to an infinite promise if the timeout is disabled (needed in Vitest for debugger support). This PR adds a $close method that works similarly to the abort controller (will throw an error in pending promises) - should we use the abort controller instead?
