Reorganize numeric expression modules

[jsiirola]

Fixes # .

Summary/Motivation:

This PR starts the process of reorganizing the numeric expression system to reduce the complexity induced by circular imports in the current implementation. This is the first step in a larger update of the expression systems (working toward implementing multiple dispatch for relational and logical expressions).

Changes proposed in this PR:

• move exception definitions to pyomo.common.errors
• move value and check_if_numeric_type to pyomo.common.numeric_types
• move the NumericValue and NumericNDArray classes into expr.numeric_expr
• move helper functions (trig, Expr_it) from expr.current into expr.numeric_expr
• use attempt_import to break import loops
• (unrelated) silence the console output for some tests
