[ARM] Use getSymbolPreferLocal() in GetARMGVSymbol
This allows relaxing some relocations to symbol+offset instead of emitting
a relocation against a symbol.

Mark the $local function begin symbol as a function
While this does not matter for most targets, when building for Arm Morello,
we have to mark the symbol as a function and add size information, so that
LLD can correctly evaluate relocations against the local symbol.
Since Morello is an out-of-tree target, I tried to reproduce this with
in-tree backends and with the previous reviews applied this results in
a noticeable difference when targeting Thumb.
Background: Morello uses a method similar Thumb where the encoding mode is
specified in the LSB of the symbol. If we don't mark the target as a
function, the relocation will not have the LSB set and calls will end up
using the wrong encoding mode (which will almost certainly crash).

[ARM] Emit local aliases (.Lfoo$local) for functions
ARMAsmPrinter::emitFunctionEntryLabel() was not calling the base class
function so the $local alias was not being emitted. This should not have
any function effect right now since ARM does not generate different code
for the $local symbols, but it could be improved in the future.
