feat: blob URL support (#10045)

This commit adds blob URL support. Blob URLs are stored in a process
global storage, that can be accessed from all workers, and the module
loader. Blob URLs can be created using `URL.createObjectURL` and revoked
using `URL.revokeObjectURL`.

This commit does not add support for `fetch`ing blob URLs. This will be
added in a follow up commit.
