[Bug/Performance]: Presence doesn't check if timeout exists

[spaceemotion]

Environment

Developement/Production OS: Windows 10
Node version: 22
Package manager: pnpm@8
Radix Vue version: 1.9.11
Vue version:  3.5.13 
CSS framework: tailwindcss@3

Steps to reproduce

1. Have over a thousand menus on the screen (e.g. a long list of non-virtualized elements)
2. Load the page with the profiler open
3. See many clearTimeouts tanking the performance

Describe the bug

We got a user report where the page loads quite slow for them. Turns out they're an outlier, but they still have about 900 entries in our system, each causing 2 Dropdown menus to be rendered on the screen (in a container with a scrollbar, but still).

After some digging, I saw that the Presence system seems to be the cause:

radix-vue/packages/radix-vue/src/Presence/usePresence.ts

Line 141 in ad43ecf

ownerWindow?.clearTimeout(timeoutId)

When a menu is still invisible and hasn't been interacted with, the timeout doesn't need to be cleared, but it's called regardless. The repro link is a JS benchmark that compares:

1. calling clearTimeout even with an undefined ID
2. checking if the ID is undefined before calling clearTimeout.

It seems that not calling it seems to bring a big performance boost (at least in the benchmark). I wasn't able to test this in reality (don't have a fork of redux-vue ready).

Expected behavior

Hundreds of (closed) Dropdowns not blocking the app for seconds / hundreds of milliseconds.
