  Log Message:
  -----------
  [LLDB] Add an API to check whether a variable is writable (#208042)

IDEs may offer functionality to set a variable to a specific value.
There are many situations where this isn't actually possible, for
example, if the variable's value is a constant or the result of a
complex DWARF expression. Instead of offering to change a value only to
have it fail with an error, this API lets the IDE query whether setting
a value is generally feasible so it can hide the action where it isn't
applicable.
