From: Maksim Tiushev <mandesero at gmail.com>

This patch adds CI testing with Valgrind in three scenarios:
  - Full checks enabled.
  - No leak checks, with memory fill set to `--malloc-fill=0x00`
    and `--free-fill=0x00`.
  - No leak checks, with memory fill set to `--malloc-fill=0xFF`
    and `--free-fill=0xFF`.

+# Setup environment for Valgrind on Linux
+
+Action setups the environment on Linux runners (install requirements, setup the
+workflow environment, etc) for testing with Valgrind.
+
+## How to use Github Action from Github workflow
+
+Add the following code to the running steps before LuaJIT configuration:
+```
+- uses: ./.github/actions/setup-valgrind
+  if: ${{ matrix.OS == 'Linux' }}
