Add switch pro controller mappings and gamepad.getInputLabel

[Geokureli]

Mappings Added:

• Switch Pro Controller
• Solo L and R Switch Joycons
• Dual Joycons as single gamepad

Because Nintendo's controllers have very contradictory labelling compared to our input scheme, I thought it was important that flixel offer easy ways for devs to accurately distinguish these buttons to players. I've gone and mapped inputIDs to custom labels so they can display a string label for any button on any mapped gamepad device.

Example:

trace(myGamePad.getInputLabel(LEFT_SHOULDER), myGamePad.getInputLabel(LEFT_TRIGGER))

will have the following values:

Switch Pro: l, zl
Switch Left Joycon: sl, zl
Switch Right Joycon: sl, null
XBox/XInput: lb, lt
PS4/Vita: l1, l2
Wii+Nunchuck: c, z

I don't have a switch pro controller, so not too much I can test here. @larsiusprime Do you maybe want to take a look at this?

And if someone knows why flash behavior seems inconsistent, I'd love to know. At first I got seemingly random button presses and axis changes until I update my FP debugger, then it worked perfectly. The next day it was back to chaos

Decided to trim down FlxGamepad.checkStatus @Gama11 brought up that it's a bit hefty for an inline function in #2253

[larsiusprime]

Yeah I have these devices. I'll try to test this stuff next week if someone pings me a reminder; only chief concern is to make sure that adjustments meant for PC behavior don't trip us up with the behavior of the native controllers on the actual Switch.

Can always wrap this in #if !switch if it messes with current switch mappings. I don't have a Switch SDK so this isn't something I can look into

@larsiusprime Ping.

Ok, I'll just have to assume the changes are good then.
