logd: Allow flags "eng" and "svelte" in boolean
- enhance property_get_bool, drop property_get_bool_svelte
- enhance base properties with ro and persist variants
- update and fortify README.property
- primarily move auditd and kernel logger into a realm where
they can be controlled by build properties.
- Move logd.klogd to logd.kernel, and add ro.logd.kernel
and persist.logd.kernel.
- Add ro.logd.auditd and persist.logd.auditd.
- Document persist.logd.security
- Document log.tag and persist.logd.tag properties.
- Document ro.logd.size, persist.logd.size and logd.size
properties.

The properties that logd responds to are:

sent on to dmesg log
-logd.klogd bool depends Enable klogd daemon

+persist.logd.size number ro Global default size of the buffer for
all log ids at initial startup, at

-persist.logd.filter string Pruning filter to optimize content,
- default is ro.logd.filter or
- "~!" which means to prune the oldest

-persist.logd.timestamp string The recording timestamp source. Default
- is ro.logd.timestamp. "m[onotonic]" is

+persist.log.tag string build default for log.tag
+log.tag.<tag> string persist The <tag> specific logging level.
+persist.log.tag.<tag> string build default for log.tag.<tag>

+- bool+ - "true", "false" and comma separated list of "eng" (forced false if
+ ro.build.type is "user") or "svelte" (forced false if ro.config.low_ram is
+ true).
+- svelte - see ro.config.low_ram for details.
+- svelte+ - see ro.config.low_ram and ro.build.type for details.
+- ro - <base property> temporary override, ro.<base property> platform default.
+- persist - <base property> override, persist.<base property> platform default.
+- build - VERBOSE for native, DEBUG for jvm isLoggable, or developer option.
+- number - support multipliers (K or M) for convenience. Range is limited
to between 64K and 256M for log buffer sizes. Individual log buffer ids
such as main, system, ... override global default.
- Pruning filter is of form of a space-separated list of [~][UID][/PID]
