accel/tcg: Access tcg_cflags with getter / setter 

Access the CPUState::tcg_cflags via tcg_cflags_has() and
tcg_cflags_set() helpers.

Mechanical change using the following Coccinelle spatch script:

  @@
  expression cpu;
  expression flags;
  @@
  -     cpu->tcg_cflags & flags
  +     tcg_cflags_has(cpu, flags)

  @@
  expression cpu;
  expression flags;
  @@
  -     (tcg_cflags_has(cpu, flags))
  +     tcg_cflags_has(cpu, flags)

  @@
  expression cpu;
  expression flags;
  @@
  -     cpu->tcg_cflags |= flags;
  +     tcg_cflags_set(cpu, flags);

Then manually moving the declarations, and adding both
tcg_cflags_has() and tcg_cflags_set() definitions.
