  Log Message:
  -----------
  [flang][hlfir] Added hlfir.get_length to inquire char length from hlfir.expr.

We will use hlfir.get_length to lower inquiries of char length
applied to hlfir.expr character values.

  Log Message:
  -----------
  [flang][hlfir] Codegen for hlfir.get_length.

Lower hlfir.get_length into the char length inquiry of the bufferized
entity. In some cases the codegen will fail with
`hlfir.associate of hlfir.expr with more than one use` - this will be fixed
separately (after D154521).

Depends on D154560

  Log Message:
  -----------
  [flang][hlfir] Lower char length inquiry via hlfir.get_length.

ApplyOp provides the type parameters in its argument, so we can
take it from there. For hlfir.expr block arguments (such as with
user-defined assignments) we use hlfir.get_length in lowering.
