Add support for wrap-git meson subprojects

[Copilot]

Meson subproject support only handled wrap-file types. Projects using wrap-git subprojects (like ffmpeg with nasm-binary) would fail.

Changes

Extended wrap parser (parse_wrap()):

• Detects wrap type from section header: [wrap-file] or [wrap-git]
• Skips non-data sections like [provide]
• Validates required fields per type:
  • wrap-file: directory, source_url, source_filename, source_hash
  • wrap-git: url, revision

Added git subproject fetcher (meson_subprojects_git_fetch()):

• Clones git repositories into subprojects/ directory
• Supports optional depth parameter for shallow clones
• Supports optional directory parameter for custom checkout location
• Checks out specified revision after clone

Updated subproject extraction (meson_subprojects_extract()):

• Routes to file downloader or git cloner based on wrap type
• Maintains offline mode behavior for both types

Example

# Now supported
[wrap-git]
url = https://gitlab.freedesktop.org/gstreamer/meson-ports/nasm-binary.git
revision = HEAD
depth = 1

[provide]
program_names = nasm

Original prompt

This commit 013e32c added support to downloading and using meson subprojects, but only wrap-file meson wraps were supported. wrap-git meson subprojects are missing.

Can you implement that updating cerbero/build/source.py ?
