test/bitops: check worker lcore availability

Coverity is not able to understand that having 2 lcores means that
rte_get_next_lcore(-1, 0, 1) can't return RTE_MAX_LCORE.
Add a check.

test/bitops: fix 32-bit atomic test spurious failure

The macros generating the parallel test for atomic test-and-
[set|clear|flip] functions used a 64-bit reference word when assuring
no neighbouring bits were modified, even when generating code for the
32-bit version of the test.

This issue causes spurious test failures on GCC 12.2.0 (the default
compiler on for example Debian 12 "bookworm"), when optimization level
2 or higher are used.

The test failures do not occur with GCC 11, 12.3 and 13.2.

To the author, this looks like a promotion-related compiler bug in GCC
12.2.

Add functionality to test and modify the value of individual bits in

These functions have no implications on memory ordering, atomicity and
