HDMI compliancy: Assert +5V according to section 4.2.7 of the specification version 1.4b

This very line of code was a game changer when it comes to HDMI compatibility:

   ct_hpd_o           : out   std_logic := '1';

It is here in the R3 version of the core:

https://github.com/MJoergen/C64MEGA65/blob/develop/M2M/vhdl/top_mega65-r3.vhd#L43C72-L43C160

TODO:

• [x] Add this to the R4 board implementation
• [x] Have a test user confirm that it works (either by measuring the +5V or by using one of the devices, for example HDMI capture device, that do not work without these +5V)
• [x] Add this to the R5 board implementation
• [x] Have a test user confirm that it works

Why "confirm that it works?": Because the R4 and R5 boards a new and might have hardware-bugs on the board

@MJoergen You can assign this to me after you fixed it in the code for the "confirm" part of the job: I know the users and the issue quite well.

@MJoergen Is this comment that you made here: https://github.com/MJoergen/C64MEGA65/issues/82#issuecomment-1773813754 related to this? If yes, then we could check the boxes "Add this to the board implementation" and only have people test it - or - if we are sure that this power-supply you are talking about is really hardwired on the board, we can also just close this one.

[MJoergen]

Yes, this is indeed related. I'm pretty sure it just "works out of the box", but it would be nice to have someone confirm it.

Deft confirmed that the C64 core V5.1 RC1 on an R5 board works fine with his HDMI capture device.
