Clang does not implement P1814R0 (class template argument deduction
for alias templates), so it can't deduce the template arguments
for range_bound, but it can for interval_bound, so switch to that.
Using the modern name rather than the compatibility alias is preferred
anyway.
Closes#7422
In bd6855e, we reverted to Boost ranges and commented out the concept
check. But Boost has its own concept check, which this patch enables.

Closes#7471
Replace operator_type with the nicer-behaved oper_t in CQL parser and,
consequently, in the relation hierarchy and column_condition.
After this, no references to operator_type remain in live code.

operator_type is awkward because it's not copyable or assignable.
Replace it in expression representation with a new enum class, oper_t.

Move the classes representing CQL expressions (and utility functions
on them) from the `restrictions` namespace to a new namespace `expr`.
Most of the restriction.hh content was moved verbatim to
expression.hh. Similarly, all expression-related code was moved from
statement_restrictions.cc verbatim to expression.cc.
