Add support for riscv32imac-esp-espidf

[madmo]

esp32c6 and esp32h2 use the riscv32imac-esp-espidf target

Thanks lgtm, but I'm not very familiar with riscv targets, so I would also like review from *-esp-espidf target maintainers @ivmarkov @MabezDev

[ivmarkov]

Hmmm, let me take a deeper look tomorrow. For one, I don't see there a definition of the older riscv32imc-esp-espidf target (which is used for esp32c3). Or am I blind? :)

@madmo Can you elaborate a bit what is your use case?

@ivmarkov riscv32imc-esp-espidf is some 10 lines down in the same file, but was already there. Probably because the c3 was released way earlier.

Sure, my use case is that I have a cargo based esp32c6 project which is mostly rust code 🥳. For some tiny functionality I want to re use a existing single file C library. Switching the whole project to a CMake based build feels overkill.

@madmo Ah yes, I'm blind indeed. :)

If I could ask you a favor: while we are at it, would you mind extending your PR to also include mapping for the riscv32imafc-esp-espidf target as well? This target was upstreamed recently, but we forgot about cc-rs there as well. Thanks in advance!

@NobodyXu I'm fine with the change - and as per above - I would also suggest we upstream support for the riscv32imafc-esp-espidf too.

Thank you @madmo @ivmarkov !

I would accept a separate PR adding support to it!
