Passing a Theme object into createTheme increases compile time

[possum-enjoyer]

Steps to reproduce

Steps:

1. Open this link to live example: https://stackblitz.com/edit/github-jgrb4bnu-1angvf1e?file=src%2FcreateTheme.tsx
2. stop the vite dev server
3. run npm run tsc

Current behavior

Compiling the presented code leads to a long compile time of about 3.8 seconds with a diagnostics like this:
The Diagnostics should look somewhat like this:
Files: 668
Lines: 105797
Identifiers: 106872
Symbols: 215281
Types: 51020
Instantiations: 450384
Memory used: 0K
I/O read: 0.02s
I/O write: 0.00s
Parse time: 0.40s
Bind time: 0.09s
Check time: 3.27s
Emit time: 0.00s
Total time: 3.77s

Expected behavior

The compile time should be much much lower for a small project like this and by changing line 16 and 17 the compile time goes down to 0.8 seconds with a diagnostics like this:

Context

When passing a Theme Object into the createTheme function, instead of some ThemeOptions. the compile time increases due to circular depencencies. This problem is adresses in this PoC: #47069 and would be fixed by it, but currently this leads to a long compile time.

Maybe a little warning on the createTheme page would be enough so Users know that they should not do that (or cast theme as ThemeOptions)
