[Feat]: deploy multiple SCPs to a single OU or account

### Describe the feature

Hi Team,

Is it possible to deploy multiple SCPs to a OU or account via ADF, I think at the moment we can only deploy 1 SCP per OU that too has a maximum possible file size of ~5KB.
Is there any ETA when such a feature will be added to the upcoming ADF versions?

This is our OU structure (example) -
/adf-bootstrap
- ou1
- scp.json
- sub ou 1
-scp.json
- ou2
- scp.json

Can we have something like this -
/adf-bootstrap
- ou1
- scp.json
- scp.json
- sub ou 1
-scp.json
- ou2
- scp.json
- scp.json

### Use Case

This will allow the user to deploy multiple SCPs per OU/account as at the moment only one SCP is allowed which has a upper limit on the file size ~5KB

### Proposed Solution

_No response_

### Acknowledgements

- [x] I may be able to implement this feature request

Start with the scp.json examples in the described /adf-bootstrap OU and account layout, then locate ADF’s current single-SCP handling. Define how multiple policies should be identified and applied, including the existing ~5 KB constraint; the issue names no test or implementation file, so add coverage after finding the relevant entry point.
