[PATCH 2/2] exec/gen-icount.h: Add missing "exec/exec-all.h" include

[Philippe Mathieu-Daudé]

When including "exec/gen-icount.h" we get:

  include/exec/gen-icount.h: In function ‘gen_tb_start’:
  include/exec/gen-icount.h:40:9: error: implicit declaration of function 
‘tb_cflags’ [-Werror=implicit-function-declaration]
     40 |     if (tb_cflags(tb) & CF_USE_ICOUNT) {
        |         ^~~~~~~~~
  include/exec/gen-icount.h:40:9: error: nested extern declaration of 
‘tb_cflags’ [-Werror=nested-externs]
  include/exec/gen-icount.h:40:25: error: ‘CF_USE_ICOUNT’ undeclared (first use 
in this function); did you mean ‘CPU_COUNT’?
     40 |     if (tb_cflags(tb) & CF_USE_ICOUNT) {
        |                         ^~~~~~~~~~~~~
        |                         CPU_COUNT

Since tb_cflags() is declared in "exec/exec-all.h", include this
header in "exec/gen-icount.h".
