Attestation: Free JSON from the Wasm module heap (#2803)
The JSON evidence is allocated on the module instance heap, but no API
was given to dispose of this memory buffer. The sample mentions using
the function free, which behaves differently depending on the
execution context.

This fix provides a new function called librats_dispose_evidence_json,
enabling freeing the JSON evidence directly from the Wasm app.

Update cmake files and wamr-test-suites to support collect code coverage (#1992)
Support collecting code coverage with wamr-test-suites script by using
lcov and genhtml tools, eg.:
  cd tests/wamr-test-suites
  ./test_wamr.sh -s spec -b -P -C

The default code coverage and html files are generated at:
  tests/wamr-test-suites/workspace/wamr.lcov
  tests/wamr-test-suites/workspace/wamr-lcov.zip

And update wamr-test-suites scripts to support testing GC spec cases to
avoid frequent synchronization conflicts between branch main and dev/gc.

Create module hash for each module in SGX lib-rats (#1745)
Current SGX lib-rats wasm module hash is stored in a global buffer,
which may be overwritten if there are multiple wasm module loadings.
We move the module hash into the enclave module to resolve the issue.

And rename the SGX_IPFS macro/variable in Makefile and Enclave.edl to
make the code more consistent.

And refine the sgx-ra sample document.

linux-sgx: Improve the remote attestation (#1695)
The current implementation of remote attestation does not take into
account the integrity of the wasm module. The SHA256 of the wasm
module has been put into user_data to generate the quote, and more
parameters are exposed for further verification.

linux-sgx: Improve the documentation of SGX-RA sample (#1679)
Improve the documentation for setting up SGX-RA using WAMR, based on
the feedback in #1670.

This notably highlights the dependency on Intel PCS and PCCS and how to
install/configure them.
