Fixing duplicate macro definition in umbrella edoc

Update vendored in hex_core to version 0.5.1

When in umbrella mode (or through multiple profiles), users can specify
macros for EDocs based on either the {def, ...} or the {macros, ...}
arguments.

This patch replaces the prior options merging for umbrellas to use the
rebar3 tup_umerge utils to remove identical duplicates while preserving
correct ordering, and manually merges the {macros, ...} definitions
while ke eping the correct precedence rules since these appear (given
their behaviour) to be all individually extracted and passed as `{d,
...}` to  the compiler so that epp expands them. This compiler
function freaks out on any re-defined macros and explodes.

Do note that the macros with `{def, ...}` are edoc macros and do not
suffer from that issue, safely deduplicating multiple definitions.

version 0.5.1 is a maintenance release of hex_core specifically for
 rebar3 which contains a configuration update. Prior to v0.5.1 if no
 repo_organization key was set this could result in a function clause
 error. The behavior is to now set repo_organization to undefined in
 this case.

Repair edoc functionality on rebar3 itself

de-duplicate dependency list in rebar_compiler_erl.erl

Fix reloading logger_level

OTP kernel application use "logger_level" configuration for configuring
level in primary configuration.
rebar3 uses "logger_info" for this purpose - ths is little bit confusing
and probably mistake.
This commit will unify behavior between kernel and rebar3o

Bump cth_readable to fix lager on OTP-21+

This adds an additional loading and merging of options for EDoc using
the values from the top-level along with those specified in the
rebar.config of an umbrella application.

The app-specific config values are prepended to the global ones; this
can likely cause some problems with manual path handling, but is
unlikely to happen in practice and the rest seems to work fine based on
order

Fixes the issue in #2114
