[feature + performance] add JSON logging format (#4355)

# Description

Adds JSON logging as an optional alternative log output format. In the process this moves our log formatting itself into a separate subpkg to make it more easily modular, and improves caller name getting with some calling function name caching.

# Available Go build tags, with explanation, followed by benefits of enabling it:
# - kvformat: enables prettier output of log fields (slightly better performance)
# - timetzdata: embed timezone database inside binary (allow setting local time inside Docker containers, at cost of 450KB)
# - nootel: disables compiling-in otel support (reduced binary size)
# - noerrcaller: disables caller function prefix in errors (slightly better performance, at cost of err readability)
