shim: user switcher process management struct
test / test (push) Successful in 19s Details
This change moves all user switcher and shim management to the shim package and withholds output while shim is alive. This also eliminated all exit scenarios where revert is skipped.

internal: wrap calls to os standard library functions
test / test (push) Successful in 19s Details
This change helps tests stub out and simulate OS behaviour during the sealing process. This also removes dependency on XDG_RUNTIME_DIR as the internal.System implementation provided to App provides a compat directory inside the tmpdir-based share when XDG_RUNTIME_DIR is unavailable.

app: move wayland mediation to shim package
test / test (push) Successful in 29s Details
Values used in the Wayland mediation implementation is stored in various struct fields strewn across multiple app structs and checks are messy and confusing. This commit unifies them into a single struct and access it using much better looking methods.

app: move app ID to app struct
App ID is inherent to App, and it makes no sense to generate it as part of the app sealing process.

app/share: fix order to ensure SharePath before any of its subdirectories
shareTmpdirChild happened to request an ephemeral dir within SharePath and was called before shareRuntime which ensures that path. This commit moves SharePath initialisation to shareSystem and moves shareTmpdirChild into ShareSystem. Further cleanup and tests are desperately needed for the app package but for now this fix will have to do.

app: port app to use the system package
This commit does away with almost all baggage left over from the Ego port. Error wrapping also got simplified. All API changes happens to be internal which means no changes to main except renaming of the BaseError type.

helper/bwrap: ordered filesystem args
The argument builder was written based on the incorrect assumption that bwrap arguments are unordered. The argument builder is replaced in this commit to correct that mistake.

app: migrate to new shim implementation
Both machinectl and sudo launch methods launch shim as shim is now responsible for setting up the sandbox. Various app structures are adapted to accommodate bwrap configuration and mediated wayland access.

app: tag ACL operations for revert
ACL operations are now tagged with the enablement causing them. At the end of child process's life, enablements of all remaining launchers are resolved and inverted. This allows Wait to only revert operations targeting resources no longer required by other launchers.

app: clean up interactions and handle all application state and setup/teardown
There was an earlier attempt of cleaning up the app package however it ended up creating even more of a mess and the code structure largely still looked like Ego with state setup scattered everywhere and a bunch of ugly hacks had to be implemented to keep track of all of them. In this commit the entire app package is rewritten to track everything that has to do with an app in one thread safe value.

In anticipation of the client/server split also made changes:
- Console messages are cleaned up to be consistent
- State tracking is fully rewritten to be cleaner and usable for multiple process and client/server
- Encapsulate errors to easier identify type of action causing the error as well as additional info
- System-level setup operations is grouped in a way that can be collectively committed/reverted
  and gracefully handles errors returned by each operation
- Resource sharing is made more fine-grained with PID-scoped resources whenever possible,
  a few remnants (X11, Wayland, PulseAudio) will be addressed when a generic proxy is available
- Application setup takes a JSON-friendly config struct and deterministically generates system setup operations
