Support per-rule options, and add virtual option to C++ code generation (#364)

The format of g4 files has been supporting per-rule options as
`RuleName options { optionName=value; } : ...;` for a long time,
and ANTLRv4 has been supporting at least one such option
(`caseInsensitive`) since 4.10.

This commit adds support for per-rule options in general (i.e.,
such options are parsed and stored in internal data structures),
and defines the `virtual` option (both at grammar and rule levels)
to control the C++ code generation, i.e., whether methods
corresponding to grammar rules should be virtual or not.

As a result, this change enables the Custom.g4 test case among the
C++ grammar tests. (The Python counterpart is adapted accordingly.)
