  [fir] Add fir.embox conversion

Convert a `fir.embox` operation to LLVM IR dialect.
A `fir.embox` is converted to a sequence of operation that
create, allocate if needed, and populate a descriptor.

Current limitiation: alignment is set by default but should be retrieved in the specific target.

This patch is part of the upstreaming effort from fir-dev branch.
