Update build h3 script to have the option to build quiche with openssl/quictls

[brbzull0]

Update build_h3_tools.sh to let user to build quiche+quictls instead of boringssl.

https://github.com/apache/trafficserver/pull/10672 can be used to let ATS build with openssl/quictls and https://github.com/apache/trafficserver/pull/10872 can be used to build quiche with openssl/quictls support.

Building ATS

After you run the build_h3_tools.sh quictls you'll need to set the:

• LD_LIBRARY_PATH to point to the openssl-quictls lib folder for this to work, and
• PKG_CONFIG_PATH should be set to the openssl-quictls pkgconfig folder
