[vm] Eliminate Mutex/Monitor indirection where possible

In many cases, the Mutexes and Monitors have to be marked "mutable"
because they're used to synchronize const accessor methods.

Small text segment improvement for Product builds:

$ size dart.{arm,x64}.{before,after}
   text	   data	    bss	    dec	    hex	filename
19726069	 409960	 392332	20528361	1393ce9	dart.arm.before
19725525	 409960	 392332	20527817	1393ac9	dart.arm.after
22576021	 600376	1782824	24959221	17cd8f5	dart.x64.before
22574821	 600376	1782824	24958021	17cd445	dart.x64.after
