refactor(@angular-devkit/core): use picomatch for PatternMatchingHost glob support

The glob support in the `PatternMatchingHost` class now uses the capabilities of the
`picomatch` package to convert glob strings into regular expressions. This removes
custom string replacement code that previously was used. The `picomatch` package is
already used by `@angular-devkit/build-angular` and is present in the repository but
is a new dependency for the `@angular-devkit/core` package specifically.
