verilog: Move lexer location variables from global namespace to `VERILOG_FRONTEND` namespace.

Rupert Swarbrick 6aa0f72ae9 Silence spurious warning in Verilog lexer when compiling with GCC
The chosen value shouldn't have any effect. I considered something
clearly wrong like -1, but there's no checking inside the generated
lexer, and I suspect this will cause even weirder bugs if triggered
than just setting it to INITIAL.

Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.

Udi Finkelstein ac10e7d96d Initial implementation of elaboration system tasks
(IEEE1800-2017 section 20.11)
This PR allows us to use $info/$warning/$error/$fatal **at elaboration time** within a generate block.
This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.

The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST
