* fix for 45006
* treat setters like getters in preceding commit; move test accordingly
* fix test baselines
* changes per code review
in `getContainerFlags`, move cases for get/set accessors
to fallthrough into the block that currently handles MethodDeclaration;
so get/set accessors and method declarations all get the same container flags,
such that during `bindContainer`, `startFlow.node` is assigned to
getters/accessors
(this changes a public api in tsserverlibrary.d.ts and typescript.d.ts
by adding `GetAccessorDeclaration` and `SetAccessorDeclaration` to the type
of `FlowStart.node`)
consolidate predicates checking whether a node is either a get or set
accessor, into `isObjectLiteralOrClassExpressionMethodOrAccessor`
(formerly `isObjectLiteralOrClassExpressionMethod`)
annotate updated test with `@target: es2020`
* fix `isObjectLiteralOrClassExpressionMethodOrAccessor`
require that Getter/Setters are parented by an ObjectLiteralExpression or ClassExpression
