### Problem description
When the close button is clicked, `ImGui::BeginPopupModal()` sets the
bool passed into the second parameter (p_open) to false. However, the
closing logic did not take this into account, making it difficult to
actually close modal popups.
For example, closing the "Export pattern File" modal took several clicks
on the "X" button, now it closes instantly.
### Implementation description
I added an additional check for the `open` variable being `false` in the
logic that checks the closing condition.

### Problem description
This PR aims to address #1645 that caused the built in file provider's
change monitor to trigger the notification popup dialog multiple times
in a row after multiple external file changes.
### Implementation description
I added an additional boolean field
`m_changeEventAcknowledgementPending` that tracks whether there are any
pending or unacknowledged change notification dialogs to prevent further
dialogs from being opened. The flag is only reset to its initial value
once the user has acknowledged the first `PopupQuestion` dialog.
Since the file is reloaded only after the user clicks 'Yes', it is
unnecessary to ensure that only the latest popup is acknowledged.

### Problem description
The framerate limiter doesn't work when inputs are being sent (eg mouse
cursor moving over the window), because `glfwWaitEventsTimeout` returns
early when it encounters an event.
### Implementation description
I made it sleep for the remaining time when that happens.
