FSharpMemberOrFunctionOrValue.DeclarationLocation returns wrong location for auto property

[auduchinok]

Consider this example:

module Module

type T() =
    member val Prop int = 1 with get, set

T().Prop

Get GetAllUsesOfAllSymbolsInFile and find the symbol for the Prop usage on the last line. This symbol reports get range as its declaration range instead of Prop range.

This seems to have regressed in #15589.
