testsuite: fix flaky foundation Divisible / mulIntMayOflo# tests (#27222)
Since the LCG was widened to 64 bits and the seed randomised per CI run
(commit 2d30f7d3400 "Vendor mini-QuickCheck for testsuite"), two latent
bugs in the foundation test surface stochastically:
* The Divisible property `(x `div` y) * y + (x `mod` y) == x` raises
ArithException(Overflow) when (a, b) = (minBound, -1) for fixed-width
signed Integral types. Split testNumber/testDivisible into Bounded and
unbounded variants and skip just that one pair, gated by
`(minBound :: a) < 0` so unsigned types lose no coverage.
* The `mulIntMayOflo#` test compared raw Int# bit-for-bit, but the primop
is only specified to return 0/non-zero -- the exact non-zero indicator
legitimately differs between backends and inlining choices. Add a
dedicated `testPrimopMayOflo` helper that only compares zero / non-zero.
Also fix the long-standing typo "Dividible" -> "Divisible" in identifiers.

testsuite: catch and display exceptions in MiniQuickCheck
Exceptions raised while evaluating a property are now caught and reported
as a normal failure (with arguments and seed), instead of aborting the
test.

interface-stability/base: don't distinguish ws-32
The interface of base is identical when the Word size is 32bits.
Therefore, there is no need to have another file for this case.
So, we delete it.
