Changes since v3:
- Replace for_test with if_test, a more robust conditional-like macro.
It stores description and location like v1, but without using strbuf.
- Drop patch 7 for t-strbuf to avoid hindering Kyle's cleanup idea.
Side note: Created with --creation-factor=60, as the default of 999 in
v2.46.0 pairs dropped patch 7 with new patch 4 and reports old patch 4
as dropped, which is confusing.

## Commit message ##
- t-reftable-basics: use for_test
+ t-reftable-basics: use if_test
The macro TEST takes a single expression. If a test requires multiple
statements then they need to be placed in a function that's called in
the TEST expression.
Remove the overhead of defining and calling single-use functions by
- using for_test instead.
+ using if_test instead.
Run the tests in the order of definition. We can reorder them like that
because they are independent. Technically this changes the output, but
