fix for 45006 (#45020)
* 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

Fix unassignable properties by adding undefined with exactOptionalPropertyTypes (#45032)
* Simple first version

Doesn't cover or test any complicated variations.

* Lots of cases work

Destructuring does not. But

- skipping node_modules and lib.* does.
- call expressions does
- property access, including with private identifiers, does

* Support variable declarations, property assignments, destructuring

As long as it's not nested

* More cleanup

* skip all d.ts, not just node_modules/lib

* Offer a codefix for a lot more cases

* remove incorrect tuple check

* Use getSymbolId instead of converting to string

Co-authored-by: Andrew Branch <andrewbranch@users.noreply.github.com>

* add test + switch to tracking number symbol ids

* Address PR comments

* Exclude tuples from suggestion

* Better way to get error node

Plus add a check that errorNode is an argument to the call, not the
call's expression.

* fix semicolon lint

* fix another crash

* Simplify: add undefined to all optional propertie

whether or not somebody tried to assign undefined to them in the
erroneous assignment

* remove fix-all
