Fix confusion between parameters vs arguments in parser.

Fix confusion between parameters vs arguments in parser.

There are two changes:

1. Modify `_isPeekGenericTypeParametersAndOpenParen` to call
`_skipTypeParameterList` instead of `_skipTypeArgumentList`.  This
fixes parsing of generic function declarations like `f<@a T>() {}`,
which previously couldn't be parsed because `<@a T>` isn't a valid
type argument list.

2. Rename `_isLikelyParameterList` to `_isLikelyArgumentList` to
reflect how it is actually used (and what it actually does).  This is
no user-visible effect.
