The main tree, tooltips, and search results once showed the parameter
list of a parameterized property; the ambience lost that when property
rendering went through the converted AST node, whose C# property syntax
cannot carry parameters. Take the parameter list from the symbol
instead and render it in parentheses (matching VB.NET usage syntax and
distinguishing these properties from indexers).

A dynamic index access (a[b]) gave its IndexerExpression a
DynamicInvocationResolveResult with no symbol, so the brackets carried no
tooltip. Synthesize an indexer (FakeProperty, IsIndexer) on the target
type with the index parameters typed from the callsite delegate, and
attach it. Route it hover-only by detecting a DynamicInvocationResolveResult
directly on the node - which also covers an invoke-member's own
parentheses, so those stop producing a dead navigation link too.

Lock the hover content the dynamic-tooltip work produces. Ambience-level
cases (CSharpAmbienceTests) pin that SpecialType.Dynamic renders as
"dynamic" and that a synthetic dynamic method renders its return and
per-argument types - including the full hover form, confirming the
unnamed synthetic parameters collapse to their types with no dangling
name. An end-to-end case (HoverOnlyReferenceTests) decompiles a dynamic
call and renders the symbol GetSymbol hands back, exercising the actual
synthesis (argument typing from the callsite delegate), not a hand-built
stand-in.
