Add -l EquationWarnings and warning context in Booster (#3937)

Fixes #3927

This PR disables the display of the three equation-related warning in
Booster by default. They can be re-enabled by the flag `-l
EquationWarnings`, which is a shorthand to the context expression
`--log-context booster>(simplification *|function *)>warning`.
