web: fix TypeScript conflicts with TextEncoder and TextDecoder

In TypeScript, TextEncoder and TextDecoder are global types when
targeting the DOM environment, causing conflicts when importing these
classes from Node’s util module. To avoid these conflicts, TextEncoder
and TextDecoder from util have been imported with different names
(NodeTextEncoder, NodeTextDecoder) and assigned to globalThis with
explicit type assertions.
