kmem: capDL memory analyzer

Script that analyzes the CAmkES-generated capDL spec for memory use.

By default the memory footprint of each "component" is displayed.
(Shared memory regions are also displayed separately as it's unclear
which of multiple components to charge.)  The -d option gives each
component a breakdown by memory type:

- "elf": data loadeed from .text or .data ELF segments,
- "bss": zero-initialized memory,
- "ipc_buffer": CAmkES-generated per-thread IPC buffers,
- "stack": CAmkES-generated thread stacks,
- "copyregion": unmapped VSpace regions, and
- "mmio": device-backed memory, typically used to access MMIO registers
   but also used to reach Renode-loaded data like the cpio archive of
   builtin applications & models

(NB: mmio + copyregion sections do not count against memory use as they
are allocated from dedicated memory that does not have physical memory
backing).

By default the last release build will be analyzed (also selected with
the -R option). The -D option can be used to select the last debug build.
