Subject: [PATCH] fix(bb): initialize element::infinity() (#4664)

Points at infinity are rare enough that we can initialize this to reduce
MSAN (C++ memory sanitizer) noise without performance loss. Caused
uninitialized memory errors in kzg test (which likely shouldn't be
creating points at infinity, anyway)
