Avi Kivity f165b396fd schema_builder: make shard_count an explicit constructor parameter
A recent Seastar update deprecated smp::count and introduced
this_smp_shard_count() as a replacement. One difference is that
this_smp_shard_count() wants to run on a reactor thread.

This poses a problem for non-reactor tests (BOOST_AUTO_TEST_CASE)
that nevertheless use a schema, as the schema_builder constructor
references smp::count. If we replace it with this_smp_shard_count()
then it will crash when running without a reactor.

To fix, remove the implicit this_smp_shard_count() call from raw_schema's
constructor and require callers to pass shard_count explicitly to
schema_builder. This allows tests that don't run on a reactor thread
to construct schemas without crashing.

Production code and reactor-based tests pass this_smp_shard_count().
Non-reactor test files (expr_test, keys_test, nonwrapping_interval_test,
wrapping_interval_test, bti_key_translation_test, range_tombstone_list_test)
pass a fixed shard count of 1.

Note: sstable_test.cc is a Seastar test file (SEASTAR_THREAD_TEST_CASE)
but also contains one plain BOOST_AUTO_TEST_CASE
(test_empty_key_view_comparison) that constructs a schema_builder without
a reactor context. This test also receives a fixed shard count of 1.
