This commit converts the `fp_sharing` tests to use the ztest framework.
In addition, this commit also introduces a behavioural change to run
the `pi` unit test separately from the `load_store` unit test, in order
to allow more manageable and diagnosable test execution.

Make fp_sharing a 'parent' test suite directory, and
rename the original fp_sharing test into
tests/kernel/fp_sharing/generic. In this
way more FP-related tests can be grouped
together in the same test directory.
