Fix multiline array/dictionary match statements

Currently array and dictionary expressions cannot be spread over
multiple lines in match statements.

Adding mutliline push/pop while parsing the pattern for bracket and
brace enables the ability for these to be multiline. This enables more
complex patterns to be matched without exceeding line limits.

Fixes #90372
