Backport of befb2e9.

The shared IIS WebSocket test application asserted that IHttpMaxRequestBodySizeFeature.MaxRequestBodySize was cleared after upgrading for both hosting models. In-process hosting requires that behavior because its read loop enforces the limit, but out-of-process hosting runs on Kestrel, which does not enforce the limit after upgrade.

Scope the assertion to in-process hosting so the following out-of-process tests do not close the WebSocket prematurely:

• OnStartedCalledForWebSocket
• CanSendAndReceieveData
• WebReadBeforeUpgrade

The same fix was applied directly to #69256 and #69301.
