[Event Request] Add PreviewMode parameter to Purchase Post events

Describe the issue

Describe the issue

Some of the Purchase posting codeunit events do not have PreviewMode parameter in it.

This makes it harder for partner to prevent their code running if the posting is in PreviewMode.

We should add PreviewMode to any events that has SuppressCommit on below codeunit:

codeunit 90 "Purch.-Post"

Expected behavior

Here's an example on codeunit 90 "Purch.-Post"

internal procedure RunWithCheck(var TransferHeader2: Record "Transfer Header")
begin
...
OnAfterProcessPurchLines(PurchHeader, PurchRcptHeader, PurchInvHeader, PurchCrMemoHeader, ReturnShptHeader, WhseShip, WhseReceive, PurchaseLinesProcessed, SuppressCommit, EverythingInvoiced, PreviewMode);
...
...
OnAfterPostPurchaseDoc(PurchaseHeader2, GenJnlPostLine, PurchRcptHeader."No.", ReturnShptHeader."No.", PurchInvHeader."No.", PurchCrMemoHeader."No.", SuppressCommit, PreviewMode);
...
end;

[IntegrationEvent(false, false)]
local procedure OnAfterProcessPurchLines(var PurchHeader: Record "Purchase Header"; var PurchRcptHeader: Record "Purch. Rcpt. Header"; var PurchInvHeader: Record "Purch. Inv. Header"; var PurchCrMemoHdr: Record "Purch. Cr. Memo Hdr."; var ReturnShipmentHeader: Record "Return Shipment Header"; WhseShip: Boolean; WhseReceive: Boolean; var PurchLinesProcessed: Boolean; CommitIsSuppressed: Boolean; EverythingInvoiced: Boolean; PreviewMode: Boolean)
begin
end;


[IntegrationEvent(false, false)]
procedure OnAfterPostPurchaseDoc(var PurchaseHeader: Record "Purchase Header"; var GenJnlPostLine: Codeunit "Gen. Jnl.-Post Line"; PurchRcpHdrNo: Code[20]; RetShptHdrNo: Code[20]; PurchInvHdrNo: Code[20]; PurchCrMemoHdrNo: Code[20]; CommitIsSupressed: Boolean; PreviewMode: Boolean)
begin
end;

• I will provide a fix for a bug

Start in codeunit 90 "Purch.-Post" and inspect each event that uses SuppressCommit, including OnAfterProcessPurchLines and OnAfterPostPurchaseDoc. Trace their invocations and declarations, then verify that every applicable event exposes PreviewMode and that the application still compiles with existing subscribers.
