[OE-core][master][PATCH] libpcre2: Enabling Ptest support

[Shaik Moin <careers.myinfo@gmail.com>]

Add tests for POSIX wrapper (pcre2posix_test), core PCRE2 engine (RunTest), and grep utility (RunGrepTest).

pcre2posix_test: Verifies the POSIX wrapper API
RunTest: Executes the core PCRE2 test suite through pcre2test
RunGrepTest: Checks pcre2grep to ensure its grep‑style matching works as expected with various patterns and input files.
