src/meta-openembedded:cmark: upgrade 0.30.2 -> 0.30.3

Changelog:
===========
  * Fix quadratic complexity bug with repeated '![[]()'.
    Resolves CVE-2023-22486. Add new pathological test.

  * Allow declarations with no space, as per spec

  * Set 'enumi*' counter correctly in LaTeX output

  * Allow '<!DOCTYPE' to be case-insensitive.
    existing spec.)

  * Fixed HTML comment scanning. Need to handle this case: '<!--> and -->'.
    Since the scanner finds the longest match, we had to
    move some of the logic outside of the scanner.

  * Fix quadratic parsing issue with repeated '<!--' (this was not
    introduced by the previous fix, and not in a released version of cmark).
    Resolves CVE-2023-22484. Add new pathological test.

  * Update HTML comment scanner to accord with commonmark/commonmark-spec#713

  * Pathological tests: half the number of repetitions, and the timeout.
    This reduces the time needed for the pathological tests.

  * Shrink 'struct cmark_node' (#446). The 'internal_offset' member is
    only used for headings and can be moved to 'struct cmark_heading'.
    This reduces the size of 'struct cmark_node' from 112 to 104 bytes on
    64-bit systems.

  * Add '-Wstrict-prototypes' and fix offending functions.

  * Fix quadratic behavior involving 'get_containing_block' (#431).
    Instead of searching for the containing block, update the tight list
    status when entering a child of a list item or exiting a list.

  * Fix 'pathological_tests.py'
    - Use a multiprocessing.Queue to actually get results from spawned
      tests processes.
    - Fix the 'allowed_failures' test.
    - Truncate actual output when printed.
    - Prepare for testing pathological behavior of the Commonmark renderer.

  * Fix source position bug with backticks
