Having it set to false caused more disruption and complaints than the silent performance regressions for true ever did. So now that the dust has settled a bit on the transition to Meson, go back to the more permissive default.

The warning that is emitted when BLAS and/or LAPACK are not found is already much more visible than it was with distutils, so this new situation is still an improvement over where we were until 1.25.x.

The change to true was done in gh-24279, this is a partial revert.

Closes gh-24200
Closes gh-24703
