[Wasm] support companion object in external interface (KT-76462)

[alex28sh]

Eliminates getters of companion object from external interfaces for inlined extension properties/methods. It relies on the structure of inlined blocks

                  VAR IR_TEMPORARY_VARIABLE name:tmp0 type:<root>.CanvasFillRule.Companion [val]
                    GET_OBJECT 'CLASS OBJECT name:Companion modality:FINAL visibility:public [companion,external] superTypes:[kotlin.Any]' type=<root>.CanvasFillRule.Companion
                  RETURNABLE_BLOCK type=<root>.CanvasFillRule origin=null
                    INLINED_BLOCK type=<root>.CanvasFillRule origin=null
                      inlinedFunctionSymbol: public final fun <get-ODDEVEN> (<this>: <root>.CanvasFillRule.Companion): <root>.CanvasFillRule [inline] declared in <root>
                      inlinedFunctionFileEntry: FILE_ENTRY path:/kt59082.kt
                      VAR IR_TEMPORARY_VARIABLE_FOR_INLINED_PARAMETER name:this type:<root>.CanvasFillRule.Companion [val]
                        GET_VAR 'val tmp0: <root>.CanvasFillRule.Companion [val] declared in <root>.box' type=<root>.CanvasFillRule.Companion origin=null
                      RETURN type=kotlin.Nothing from='{IrReturnableBlockImpl}'
                        CALL 'public final fun unsafeCast <T> (<this>: kotlin.js.JsAny): T of kotlin.js.unsafeCast declared in kotlin.js' type=<root>.CanvasFillRule origin=null
                          TYPE_ARG T: <root>.CanvasFillRule
                          ARG <this>: CALL 'public final fun toJsString (<this>: kotlin.String): kotlin.js.JsString declared in kotlin.js' type=kotlin.js.JsString origin=null
                            ARG <this>: CONST String type=kotlin.String value="oddeven"

Potentially, this could lead to losing side-effects when companion object actually exists on Js side
