feat(context): add option to use escaped path

[ldesauw]

Feature

This pull request introduces an option to used url.EscapedPath() to determine parameters instead of the usual Path.
There was already an option to use url.RawPath but this field should not be used as stated here : https://pkg.go.dev/net/url@master#URL and this caused issue when having %252F in the requested path (see #4033)
I added an option to use EscapedPath() instead.

What Changed

Added UseEscapedPath field in Engine. 
handleHTTPRequest() now set path to EscapedPath if `UseEscapedPath` is at true. 
`UseEscapedPath` will override `UserRawPath` if both are activated. 

Testing

Added TestEngineHandleContextUseEscapedPathPercentEncoded() to check that the path received by the handler is indeed the escapedPath.
Added TestEngineHandleContextUseRawPathPercentEncoded() to display the difference of behavior with the current RawPath
Added TestEngineHandleContextUseEscapedPathOverride() to test that UseEscapedPath override useRawPath.
