semihosting/console: Avoid including 'cpu.h'

semihosting/console: Avoid including 'cpu.h'

The CPUState structure is declared in "hw/core/cpu.h",
the EXCP_HALTED definition in "exec/cpu-common.h".
Both headers are indirectly include by "cpu.h". In
order to remove "cpu.h" from "semihosting/console.h",
explicitly include them in console.c, otherwise we'd
get:

  ../semihosting/console.c:88:11: error: incomplete definition of type 'struct CPUState'
     88 |         cs->exception_index = EXCP_HALTED;
        |         ~~^
  ../semihosting/console.c:88:31: error: use of undeclared identifier 'EXCP_HALTED'
     88 |         cs->exception_index = EXCP_HALTED;
        |                               ^
