fix(espidf): las cabeceras incluidas con comillas tambien resuelven libreria

Arduino trata igual #include "Lib.h" que #include <Lib.h> para librerias, y
los ejemplos de los propios fabricantes usan la forma con comillas: los de
M5Stack para el Cardputer abren con #include "M5Cardputer.h". Al escanear solo
la forma con angulos, ese sketch no llegaba siquiera al resolutor de librerias y
moria con 'fatal error: M5Cardputer.h: No such file', mientras el mismo sketch
con angulos compilaba sin problema. Cualquiera que pegue un ejemplo oficial se
daba de bruces con esto.

Se pasan ademas los nombres de los ficheros del propio sketch, para que un
#include "Common.h" local siga siendo una cabecera del proyecto y no se
confunda con una libreria.

test/backend/unit/test_espidf_compiler.py cubre ambas formas, el espaciado, las
cabeceras internas de IDF y la cabecera propia del proyecto.
