refactor: use ComPtr pattern for MSIX to avoid exception handling (#49688)

* Revert "fix: fix Windows MSIX release build errors (#49613)"

This reverts commit 4b5d5f9dd5.

Co-authored-by: Keeley Hammond <khammond@slack-corp.com>

* refactor: use WRL ComPtr pattern for MSIX to avoid exception handling

The MSIX auto-updater code was using C++/WinRT (winrt::* namespace), which requires exception handling (/EHsc). Mixing exception and non-exception handling code in the same binary is problematic at runtime. This commit refactors electron_api_msix_updater.cc to use an upstream Chromium pattern and eliminates the need for special exception handling build flags

* build: import correct packages

* build: consolidate IPackage declarations

Co-authored-by: Keeley Hammond <khammond@slack-corp.com>

* refactor: use IPackageManager/IPackageManager5/IPackageManager9 and IPackage/IPackage2/IPackage4/IPackage6 interfaces as needed for different API methods.

Also consolidates duplicate completion handler logic, fixes a bug in
RegisterRestartOnUpdate where the command line string could go out of
scope, and removes unused includes.
