Simplify and improve the sygus parser (#2266)

Currently, there is code duplication for parsing constants in sygus grammars, e.g.:
https://github.com/CVC4/CVC4/blob/master/src/parser/smt2/Smt2.g#L1048
https://github.com/CVC4/CVC4/blob/master/src/parser/smt2/Smt2.g#L2304

This PR removes this duplication by introducing a new ANTLR grammar "termAtomic" in Smt2.g.

As a result of this PR, we now parse sygus grammars with any constant we otherwise parse. This addresses known issues where CVC4 rejects grammars with floating point constants.

It also removes some unnecessary code for converting builtin kinds to their total versions.

This is work towards #2197.  We still do not support sygus grammars with non-trivial *composite* terms, such as applications of indexed function symbols.

Improvements and fixes in cegqi arithmetic (#2247)

- Randomly choose either lower or upper bounds instead of always using lower bounds (this is similar to cegqi+BV),
- Equalities are handled by processAssertions,
- Resort to *only* model values at full effort instead of trying to mix model values/bounds (this is also similar to cegqi+BV),

It also includes a core fix to computing what bound is optimal based on an ordering that incorporates virtual terms. Previously, we would consider, e.g.:
`a+b*delta > c+d*delta if a>=c and b>=d`
Whereas the correct check is lexicographic:
`a+b*delta > c+d*delta if a>c or a=c and b>d`

Fix rewriter for lambda (#2211)

The rewriter for lambda is currently too aggressive, there are cases like:

lambda xy. x = y

that are converted into an array representation that when indexing based on x gives (store y true false), which is subsequently converted to:

lambda fv_1 fv_2. fv_1 = y

where fv_1 and fv_2 are canonical free variables. Here, y is used as index but was not substituted hence is incorrectly made free.

To make things simpler, this PR disables any rewriting for lambda unless the array representation of the lambda is a constant, which hardcodes/simplifies a previous argument (reqConst=true). This fixes a sygus issue I ran into yesterday (regression added in this PR).

Some parts of the code were formatted as a result.
