Always inline SeqNext and SeqRecheck
The intention of the work done in fb9f95502 was that these functions are
inlined. I noticed my compiler isn't doing this on -O2 (gcc version
15.2.0). Also, clang version 20.1.8 isn't inlining either. Fix by
marking both of these functions as pg_attribute_always_inline to avoid
leaving this up to the compiler's heuristics.
A quick test with a Seq Scan on a table with a single int column running
a query that filters all 1 million rows in the WHERE clause yields a
3.9% speedup on my Zen4 machine.
