File Browser: Enable 5 Step Scrolling

[asizon]

What's new

A new function is added to help moving between files in the file browser, when there are many files the only way up to now to make large movements is by keeping the keyup or keydown pressed. This PR helps to scroll in a more comfortable way by activating the scroll of 5 by 5 when pressing the right key.

Verification

Enter filebrowser for example through the infrared option, with an extensive database loaded. Press right key to activate 5-step scroll and scroll up or down. Press the left key to deactivate the 5-step scrolling, once deactivated, the left key returns to have the function of going to root if it is not there yet.

@asizon after some thought on UI/UX, we decided to close this PR and implement scroll acceleration on system level. @Astrrra will be responsible for this task and it will be included in next release.

@skotopes It seems like a good solution, but not good enough to provide the user with comfort and fluidity in moving between files in the file browser. If you look at the UI of many systems you will see that they combine the two scroll options, accelerated scrolling and also more precise scrolling of 5 by 5 (even 10 by 10) which makes it easier and provides more comfort. It is also true that when enabling this new mode we should notify the user that this scrolling is active in some way (scroll bar dimensions change for example).
