The non-unified frontend had repeated issues with inlining and
generics (#49309, #51909, #52907), which led us to substantially
restrict inlining when shape types were present.
However, these issues are evidently not present in unified IR's
inliner, and the safety restrictions added for the non-unified
frontend can simply be disabled in unified mode.
Fixes#54497.

The next CL will remove the -G flag, effectively hard-coding it to its
current default (-G=3).

Don't inline a function fn that has no shape parameters, but is passed
at least one shape arg. This means we must be inlining a non-generic
function fn that was passed into a generic function, and can be called
with a shape arg because it matches an appropriate type parameter. But
fn may include an interface conversion (that may be applied to a shape
arg) that was not apparent when we first created the instantiation of
the generic function. We can't handle this if we actually do the
inlining, since we want to know all interface conversions immediately
after stenciling. So, we avoid inlining in this case.
Fixes#49309.
