Add OpenSSL related settings to CUSTOM_COMPILER_ENV_VARS

`JITServer` needs to be built with `libssl`. By default, it
is built against the `OpenSSL` installed on the build machine.
The same as when `--enable-jitserver --with-openssl=system`
is specified.

This change passes the `OpenSSL` build flags from OpenJDK to
JIT build environment.
- Add `OPENSSL_DIR`, `OPENSSL_CFLAGS`, and `OPENSSL_BUNDLE_LIB_PATH`
  to `CUSTOM_COMPILER_ENV_VARS` and `CMAKE_ARGS`.
- Bundle `libssl` if `--with-openssl=fetched --enable-openssl-bundling`
  is set.

Examples on the supported flags:
--enable-jitserver --with-openssl=fetched
--enable-jitserver --with-openssl=fetched --enable-openssl-bundling
--enable-jitserver --with-openssl=system

The JIT build change is addressed in:
eclipse-openj9/openj9#5789, eclipse-openj9/openj9#7846

This is a similar change as ibmruntimes/openj9-openjdk-jdk8#303

Issue: eclipse-openj9/openj9#5720
