Fix 5 ClangTidyReadability findings:
* function 'QuicConnectionIdHasher' has inline specifier but is implicitly inlined. For more info, see go/clang_tidy/checks/readability-redundant-inline-specifier (2 times)
* function 'ReviseFirstByteByVersion' has inline specifier but is implicitly inlined. For more info, see go/clang_tidy/checks/readability-redundant-inline-specifier (2 times)
* function 'Hash' has inline specifier but is implicitly inlined. For more info, see go/clang_tidy/checks/readability-redundant-inline-specifier

This CL looks good? Just grant approval!
This CL doesn’t look good? This is what you can do:
* Revert this CL, by replying "REVERT: <provide reason>"
* File a bug under go/clang-tidy-bug for category ClangTidyReadability if there's an issue with the CL content.
* File a bug under go/rosie-bug if there's an issue with how the CL was managed.
* For all other issues such as the formatting of the CL, please file a bug under
go/clrobot-bug.
* Revert this CL and not get a CL that cleans up these paths in the future by
replying "BLOCKLIST: <provide reason>". This is not reversible! We recommend to
opt out the respective paths in your CL Robot configuration instead:
go/clrobot-opt-out.

This CL was generated by CL Robot - a tool that cleans up code findings
(go/clrobot). The affected code paths have been enabled for CL Robot in //depot/google3/third_party/quiche/METADATA.common which is reachable following include_presubmits from //depot/google3/third_party/quic/METADATA by
following go/clrobot#how-to-opt-in. Anything wrong with the signup? File a bug
at go/clrobot-bug.
