[tools] add lldbinit The goal of this commit is to add the equivalent to gdbinit but for lldb. I've tried to replicate the commands as close as possible but I'm unsure about the jss command and hoping to get some feedback on it in addition to the bta command which I'm not sure how/when this could be used. This is probably just inexperience on my part. The lldbinit file can be placed into a directory prefixed with dot (.lldbinit) and the python script is currently expected to be in the same directory. The path to the script can be changed manually if needed as well.

[explicit isolates] Pass Isolate to Object::Print All Object::Print functions now take an Isolate* parameter. Various XX::XXPrint functions now take an Isolate if it's needed rather than calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather than DECL_PRINTER. The _v8_internal_Print_ function (intended for use in gdb) now uses Isolate::Current() to get hold of an Isolate. Reduces the GetIsolate and GetHeap count by 9 and 5 respectively. Also removes unneeded gdb/lldb macros (along with their support functions), jfv, jfm, jda and jta, since job does the same thing.
