Autotools: Add pkg-config for GMP library (#15166)

Browse Source 
GMP has pkg-config integration since 2019-08-22 (version ~6.2.0).

This optionally finds the GMP library using pkg-config or falls back to
find library on the system or with the provided configure option
argument (--with-gmp=DIR).

When using DIR argument, the pkg-config check is silently skipped.

When not using DIR argument, the GMP_CFLAGS and GMP_LIBS can be also
used to find the GMP library:

        ./configure --with-gmp \
            GMP_CFLAGS=-I/path/to/gmp/include \
            GMP_LIBS="-L/path/to/gmp -lgmp"

- Added pkg-config support to find unixODBC and iODBC for the pdo_odbc
extension.
- Added pkg-config support to find GNU MP library. As a fallback default
system paths are searched. When a directory argument is provided
(--with-gmp=DIR), it will be used instead of the pkg-config.
- Removed BC enable_pear variable check due to --enable-pear configure option
once used (use with_pear variable name).
