[binary size optimization] use regex-lite instead of regex for client crates

[FranAguilera]

What

• Replace regex with regex-lite in client-side crates (bd-crash-handler, bd-log-filter, bd-log-matcher, bd-workflows) to reduce binary size
• bd-server-stats keeps using regex since binary size is not a concern server-side
• Follow-up to use regex lite #470

Verification

Tested with bazel hello world app in this PR
