Merge ba9f50d90d33c306e96942faff271da7fb375736 into d9307dbcbbe796a64d9e0ef23452da888dd7f904

Adds a new Engine option that, when enabled, prevents global middleware
registered via Use() from being executed for 405 Method Not Allowed
responses. This allows NoMethod handlers to run without triggering
middleware that may reject the request (e.g., authentication, checksum
validation) before the 405 response can be sent.

Fixes gin-gonic/gin#4189
