Create platform teams for `loong64` and `riscv64`

[targos]

I'd like to create two new teams related to new experimental platforms. They'd be like other platform teams: no specific permissions granted. Purpose is to have generic way to ping relevant people.

Refs:

• LoongArch
  • LoongArch to Experimental tier build#3511
  • doc: add loong64 info into platform list node#50086
• RISC-V
  • RISC-V to Experimental tier build#2876
  • doc: add riscv64 info into platform list node#42251

+1 to both, and please include me in the RISC-V one when you create it.

That's great!~
