Add HomeUnit type
Since Backpack the "home unit" is much more involved than what it was
before (just an identifier obtained with `-this-unit-id`). Now it is
used in conjunction with `-component-id` and `-instantiated-with` to
configure module instantiations and to detect if we are type-checking an
indefinite unit or compiling a definite one.
This patch introduces a new HomeUnit datatype which is much easier to
understand. Moreover to make GHC support several packages in the same
instances, we will need to handle several HomeUnits so having a
dedicated (documented) type is helpful.
Finally in #14335 we will also need to handle the case where we have no
HomeUnit at all because we are only loading existing interfaces for
plugins which live in a different space compared to units used to
produce target code. Several functions will have to be refactored to
accept "Maybe HomeUnit" parameters instead of implicitly querying the
HomeUnit fields in DynFlags. Having a dedicated type will make this
easier.

testsuite: Drop --io-manager flag from testsuite configuration
This is no longer necessary as there are now dedicated testsuite ways
which run tests with WinIO.

base: Fail if `timeout` is used when exceptions are masked
As pointed out in #18580, `timeout`'s implementation assumes that
exceptions will be handled. Document and assert this precondition.
Fixes #18580.
