Documentation/git.txt: improve documentation of 'GIT_TRACE*' variables

Separate GIT_TRACE description into what it prints and how to configure
where trace output is printed to. Change other GIT_TRACE_* descriptions to
refer to GIT_TRACE.

Add descriptions for GIT_TRACE_SETUP and GIT_TRACE_SHALLOW.

'GIT_TRACE'::
If this variable is set to "1", "2" or "true" (comparison
is case insensitive), Git will print `trace:` messages on
stderr telling about alias expansion, built-in command
execution and external command execution.
If this variable is set to an integer value greater than 1
and lower than 10 (strictly) then Git will interpret this
value as an open file descriptor and will try to write the
trace messages into this file descriptor.
Alternatively, if this variable is set to an absolute path
(starting with a '/' character), Git will interpret this
as a file path and will try to write the trace messages
into it.
Enables general trace messages, e.g. alias expansion, built-in
command execution and external command execution.

'GIT_TRACE_PACKET'::
If this variable is set, it shows a trace of all packets
coming in or out of a given program. This can help with
debugging object negotiation or other protocol issues. Tracing
is turned off at a packet starting with "PACK".

See 'GIT_TRACE' for available trace output options.
'GIT_TRACE_SETUP'::
Enables trace messages printing the .git, working tree and current
working directory after Git has completed its setup phase.
See 'GIT_TRACE' for available trace output options.
'GIT_TRACE_SHALLOW'::
Enables trace messages that can help debugging fetching /
cloning of shallow repositories.
