cmake: enable out-of-source build of breakpad

Previously, Breakpad was built in its source tree instead of the
user-specified build directory, inconsistent with other external
projects and potentially causing source tree pollution.

Include path fix:

- Add ${INSTALL_DIR}/include/breakpad to include directories to fix
  FTBFS on Jammy builders

Build system improvements:
- Replace dedicated LSS submodule symlink target with PATCH_COMMAND to
  simplify the build process
- Use user-specified make command instead of hardcoded "make"
- Skip building unused process library and tools
- Link against breakpad with PRIVATE visibility unless required

Compiler flag cleanups:
- Remove -Wno-array-bounds from CFLAGS (Breakpad uses C++/CXXFLAGS)
- Remove compile-time flags incorrectly placed in LDFLAGS
- Remove '-fPIC' from CFLAGS, as it is already included by breakpad
  when building on linux hosts.
- Replace the individual -Wno-* flags with -Wno-error to cancel
  -Werror option specified by breakpad. This is more future-proof.

CMake target modernization:
- Rename libbreakpad_client to Breakpad::client following modern conventions
- Add Breakpad::breakpad header-only target to minimize dependencies
- Install library to enable proper include path prefixes
  (breakpad/client/... vs client/...)

Header dependency optimization:
- Remove Breakpad includes from popular headers, use forward declarations
- Include Breakpad headers before internal headers for better readability

debian: radosgw: add media-types packages as alternative for mime-support

Back in 2020 the '/etc/mime.types' file was split out into it's own
leaner 'media-types' Debian package [0], the previous 'mime-support'
was kept as transitional package to handle upgrades, but it did its
job and isn't included in Debian Trixie repos anymore.

So accept both, the new 'media-types' package or the legacy
'mime-support' one as valid dependency for radosgw, this ensures one
can install radosgw on newer Debian based releases while keeping it
also working for older ones.

qa: Add Teuthology test for BlueStore ESB assertion failure

Adds a test to reproduce the !ito->is_valid() assertion in BlueStore
with bluestore_elastic_shared_blobs=true on a 2+1 EC pool using a
FIO randwrite workload (512 concurrent ops, 50G, 12,500 objects).
The test deploys a 6-OSD cluster and runs FIO for 1 hour via workunit,
failing if an OSD crashes.
