[RFC] Support object types in BCMath (#13741)

Added BcMath\Number class. It is an immutable object, has methods that are
equivalent to existing BCMath calculation functions, and can also be calculated
using operators.

The existing BCMath function returned a string for each calculation, but this
class returns an object.

Added scale to bc_compare argument (#14802)

In the original specification, the scale of bc_num was directly changed
and compared.

This becomes a problem when objects are supported, so we will modify it
to compare without changing bc_num.

Fix #78238: BCMath returns "-0"

There is no negative zero in the decimal system, so we must suppress
