DX-90582: Force protobuf-3.x in vcpkg.json

Rev 3:  Reinstate builtin-baseline to match
https://github.com/Bit-Quill/arrow/blob/ccf812f46373c3830735e60a120a5dd8ad7b0eff/cpp/vcpkg.json
(tip of https://github.com/Bit-Quill/arrow/blob/BQ-flight-jdbc-driver/cpp/vcpkg.json which is what
the build job is currently configured to use by branch name)

Rev 4: Change to 3.19.4 because vcpkg doesn't work as documented and cannot use a nonexistent version
as a "version>=" lower bound.

Rev 5: Change builtin-baseline to 642a803 (current vcpkg/master tip)
as part of resolving build issues with e.g. boost-coroutine

Rev 6: Correctly change vcpkg builtin-baseline to b2fd29fec759bf49fd40bfd633204200b115a2b5

Rev 7: Update vcpkg.json protobuf "version>=" to 3.21.8

Rev 8: FORCE protobuf-3.21.8 in vcpkg.json "overrides"

Rev 9: Try using grpc-1.51.1#3 to eliminate dependency on protobuf-4.x

Rev 10: Typo in vcpkg.json

Rev 11: Also use overrides in vcpkg.conf for both grpc & protobuf

Rev 12: Try adding override to upb-2022-06-21#1 to resolve grpc build failure

Rev 13: Add xsimd to vcpkg.json as it is no longer a transitive dependency

Rev 14: Force abseil 20220623.1#0 which presumably works with Arrow @
        b050bd0d31db6412256cec3362c0d57c9732e1f2

Rev 15: Downgrade re2 for compatibility with older abseil
