Björn Steinbrink d11b48c85c Error out when using static_assert on a non-boolean value
static_assert is documented as working on static with type `bool`, but
we currently accept it on any const static and crash when the const has
an non-integral type.

This is a breaking-change for anyone who used static_assert on types
likes i32, which happened to work but seems like an unintended
consequence of the missing error checking.

[breaking-change]

Fixes #22056
