Fix exception handling errors for supervisor

[kuqin12]

Preface

Please ensure you have read the contribution docs prior to submitting the pull request. In particular, pull request guidelines.

Description

The current exception handling routine has 2 issues:

1. When it comes to page fault, the miscellaneous exception handler will print the exception context and then hand off to the specific page fault handler, which will make the log appear as the system double fault.
2. When the page fault exception occurs, the existing setup will switch the system to use a separate stack, which is hardcoded to be 4KB from the top of supervisor stack. This size is insufficient after switching to PageTableLib based page table attribute manipulations.

This change should fix both issues.
