fix(node): Vendor `InstrumentationNodeModuleFile` to fix Bun `--bytecode` crash (#21262)

`InstrumentationNodeModuleFile` from `@opentelemetry/instrumentation`
resolves `path.normalize`. When Bun's `--bytecode` compiler inlines the
module tree into a single flat bundle, it renames `normalize` to
`normalize4` and then loses the scope binding in bytecode compilation,
producing a `ReferenceError` at runtime.

Vendor a local `InstrumentationNodeModuleFile` class that calls
`path.normalize()` directly, replacing the import from
`@opentelemetry/instrumentation` in all vendored instrumentations within
`@sentry/node`.
