First support for SnR Iron165 R2 H

[Gondolindrim]

Description

This is the continuation of PR 20617 which due to the time it lasted made the merge conflicts obnoxiously big. Naturally it incorporates all feedback from that PR: thanks @drashna and @noroadsleft for the feedback!

Adds support for the Iron 165-H (hotswap) PCB. Since right now there is only a iron165r2 folder, the Iron165-S (solderable) was moved to a new folder iron165r2_s so that iron165r2_h would be used for the hotswap.

Not sure what to do about the Lint error. It claims no LAYOUT_65_ansi_blocker_tsangan() macro found yet the macro is defined on info.json

Looks like this needs a rebase due to merge conflicts.

• WS2812_DMA_STREAM has been renamed to WS2812_PWM_DMA_STREAM
• WS2812_DMA_CHANNEL has been renamed to WS2812_PWM_DMA_CHANNEL
• config.h's #define RGBLIGHT_DEFAULT_VAL is now represented in info.json/keyboard.json as rgblight.default.val:

  {
      ...
      "rgblight": {
          "default": {
              "val": 0
          }
      },
      ...
  }
