Copy //third_party/quic string libraries to //third_party/quiche
* quic_str_cat_lib -> quiche_str_cat_lib
* quic_string_piece_lib -> quiche_string_piece_lib
* quic_text_utils -> quiche_text_utils
To keep CLs small, a series of followup CLs will modify consumers of
these libraries to use the quiche variant. A final followup CL will
remove the originals from //third_party/quic.
The motivation is to expose base64 functions to our HTTPSSVC parsing
library, which will eventually land in //third_party and be shared
with Chromium via //third_party/quiche.
