In the recent codebase update (commit 8bf6fbd, 2023-12-09), a new unit testing framework written entirely in C was introduced to the Git project aimed at simplifying testing and reducing test run times. Currently, tests for the reftable refs-backend are performed by a custom testing framework defined by reftable/test_framework.{c, h}. Port reftable/record_test.c to the unit testing framework and improve upon the ported test.
The first patch in the series moves the test to the unit testing framework, and the rest of the patches improve upon the ported test.

--- Changes in v4: - Rename the tests to follow a 't_foo()' pattern instead of 'test_foo()' - Use hard-coded test input in the 10th and 11th patch

reftable/record.{c, h}. Migrate reftable/record_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
- framework.
+ framework, and renaming the tests to fit unit-tests' naming scheme.

While at it, change the type of index variable 'i' to 'size_t'
from 'int'. This is because 'i' is used in comparison against
'ARRAY_SIZE(x)' which is of type 'size_t'.
