Move distribution generator script to scripts/dev

The more proper place for shell scripts dedicated for development, and
releasing PHP should be the scripts/dev directory. Having a cleaner root
project directory helps find the main README.md and files relevant to
install PHP.

These scripts are also used by the release managers mostly who create
release packages and aren't used often by the majority of developers
working on and installing PHP.

+# This script generates PHP lexer and parser files required to build PHP. The
+# generated files are ignored in the Git repository and packaged during the PHP
+# release process into the release installation archive download. This way the
+# bison and re2c dependencies are not required to build PHP when downloading
+# release archive.
+#
+# Usage: genfiles
+#
+# Environment:
+#   The following environment variables can override default generators paths.
+#
+#     YACC    Parser generator program, default bison
+#     RE2C    Lexer generator program, default re2c
+#
+#   For example:
+#     YACC=/path/to/bison ./genfiles
+
+# Parser generator
+YACC=${YACC:-bison}
+YACC="$YACC -y -l"
+
+# Lexer generator
+RE2C=${RE2C:-re2c}
+RE2C_FLAGS="-i"
+
+# Current path to return to it later. This enables running script from any path.
