Expose SectionContext

[sovdeeth]

Problem

Testing in the addon development channel has revealed an issue when attempting to manually parse expressions, often as parts of sections or structures. The core issue is the inability for an addon to update SectionContext and tell the parser what section it's parsing. This manifests in different ways depending on the use case. In SkCheese, an infinite parsing loop can be created with the new string expression section where not updating the SectionNode in SectionContext leads to the same Node being parsed again and again, but always being given its parent node in init(). In Oopsk, it can manifest where a field in a struct instance section containing a section expression claims its parent section leading to a double-claim. In Jake's unreleased packet addon, it leads to a strange error where a nested section using an EntryValidator is given the wrong SectionNode and claims itself is an unexpected entry.

Solution

Makes SectionContext and SectionContext#modify() public for addon use.

Testing Completed

None, no logic change was made.
