Make forall a keyword (#23719)

Before this change, GHC used to accept `forall` as a term-level
identifier:

	-- from constraints-0.13
	forall :: forall p. (forall a. Dict (p a)) -> Dict (Forall p)
	forall d = ...

Now it is a parse error.

The -Wforall-identifier warning has served its purpose and is now
a deprecated no-op.

driver: Ensure we actually clear the interactive context before reloading

Previously we called discardIC, but immediately after set the session
back to an old HscEnv that still contained the IC

Partially addresses #24107
Fixes #23405

driver: Ensure we force the lookup of old build artifacts before returning the build plan

This prevents us from retaining all previous build artifacts in memory until a
recompile finishes, instead only retaining the exact artifacts we need.

Fixes #24118

testsuite: add test for #24118 and #24107

MultiLayerModulesDefsGhci was not able to catch the leak because it uses
:l which discards the previous environment.

Using :r catches both of these leaks

compiler: Add some strictness annotations to ImportSpec and related constructors
This prevents us from retaining entire HscEnvs.

Force these ImportSpecs when forcing the GlobalRdrEltX

Adds an NFData instance for Bag

Fixes #24107
