Cleanup the hyperlight-host public API #765
Description
Currently the following items are publicly exported from hyperlight-host, and I believe many of them were never intended to be public, we should fix that.
For items that are not intended to be public, but are needed by macros, we should mark them as #[doc(hidden)], and ideally be moved to a properly named module, something like _private
Crossed out are the items I believe don't need to be public.

From the things I believe should be public, they live in the following modules:
func: 9 items, most supporting theHostFunctiontrait, the only other item is theRegisterabletrait.{HostFunction, ParameterValue, ReturnType, ReturnValue, ParameterTuple, Registerable, ResultType, SupportedParameterType, SupportedReturnType}sandbox: 9 items, this is the most varied module.{config::SandboxConfiguration, initialized_multi_use::MultiUseSandbox, snapshot::Snapshot, uninitialized::GuestBlob, uninitialized::GuestEnvironment, uninitialized::UninitializedSandbox, uninitialized::GuestBinary, Callable, ExtraAllowedSyscall}error: 1 item{HyperlightError}::(crate's root): 3 items, macros andResult{log_then_return, new_error, Result}and one outlier,
hypervisor::InterruptHandle, which arguably should belong to a different module, probablysandbox.jsturtevant commentedon Aug 20, 2025
There was a Suggestion that we mark these as depreciated, we use these internally so might need to add allows as well
