1693329 - Unify the mechanics of dropping WebGPU objects

Status: RESOLVED FIXED

(Core :: Graphics: WebGPU, task)

Description

[Dzmitry Malyshau [:kvark]]

We currently have 2 mechanisms in place:

1. (old mechanism) there are individual messages from client to server: FreeBuffer, FreeTexture, etc
2. (new mechanism) the DropAction message that encodes the freeing in byte buffers.

We should port all the old logic over to the DropAction

Attachment: Update WebGPU code to use the new drop IPC

Instead of having a separate IPC message type for every kind of object ID freeing,
we are encoding this into Rust enums and passing under the same DropAction.
This saves a bunch of lines of code, and allows us to free IDs in bulk where we need it.
