esp32/mpconfigport: Enable the RV32 emitter for ESP32C3 targets.

The RV32 code emitter assumed that the arch-specific NLR was used
instead of the setjmp/longjmp based NLR code.  If the latter NLR
provider was chosen, the emitter would allocate space on the stack
for the NLR buffer but would not fill it in.

This change turns off setjmp()-based NLR and GCREGS for the ESP32C3
target, in favour of more platform-tailored alternatives.  As setjmp()
NLR is now disabled by default, the RV32 emitter can be safely enabled
by default as well for the target in question.
