746bdb7946 Fix getContextualTypeForBindingElement for arrays 
When handling an array type, the lookup should use the position index
instead of the identifier name.

Also uncomment the tests in the `staticFieldWithInterfaceContext.ts`
test which failed because of this bug.

Fixes #40158.

a320e1b554 Make getLocalSymbolForExportDefault look harder for an export 
Look for a symbol that has a `.localSymbol` property instead of blindly
using the first one.

f2d1531768 Fix location for duplicate function implementation errors 
Use only the relevant declarations (by collecting them in the for loop),
and use `declaration` if `getNameOfDeclaration` didn't work (useful for
`export default` with anonymous functions).

Fixes #39804.

Also, use `nodeIsPresent` once, and a random `?.`.
