Paul Jolly 0bd3dbed90 internal/lsp/fake: define Symbol method on Editor
In preparation for later changes to the implementation of the workspace
Symbol method, we add the Symbol method to fake.Editor. This requires
the definition of a number of associated fake types (editor-friendly,
byte-offset-based versions of protocol UTF16-based types) for example
fake.SymbolInformation and the types it references.

We also implement a basic regtest for the Symbol method, exposing Symbol
on regtest.Env like other LSP server methods. To aid with the writing of
Symbol result assertions, we provide some helper functions to simplify
the process of defining matches that are evaluated against the result
set.
